High Temperature Superconductivity ** THIS PAGE LOOKS BEST WHEN VIEWED FULL SCREEN ** Making superconducting electronics a reality, a group of dedicated people within IBM Research, both at the T. J. Watson Research Center and Zurich Research Laboratory , are aggressively pursuing superconducting science and technology. Come and explore a fantastically cool world with us! HIGHLIGHTS OF OUR RECENT WORK: "IBM Scientists move closer to understanding source of high temperature superconductivty" Scanning SQUID Microscope and the Half-Integer Flux Quantum Effect The scanning SQUID microscope is an extremely sensitive instrument used for imaging magnetic fields at the surfaces. We have used it to image vortices in special geometries of high-Tc superconductors with exactly half of the flux normally seen. WHAT WE ARE DOING: Applications of SQUIDs - Superconducting QUantum Interference Devices (SQUIDs) are the most sensitive detectors of magnetic fields in existence. At IBM we are learning how to use SQUIDs in real world applications. Symmetry of the High-Tc Superconducting Wave Function - Using a Scanning SQUID Microscope we are trying to measure how the electrons in a superconductor arrange themselves.

Andersen Group El.-Phon. QMC Resistivity saturation Electron-phonon interaction in high T c cuprates There are several signs of a rather strong electron-phonon interaction in high T c cuprates. In neutron scattering experiments, several phonons show an appreciable softening under doping, suggesting a substantial coupling to the doped holes. This is in particular the case for the oxygen half-breathing phonon at about 70 meV, where two of the four oxygen atoms, surrounding a Cu atom in the CuO plane, move towards the Cu atom. While a shell model describes other phonons quite well, it fails to describe the softening of the half-breathing phonon. In the doped system, the width of this phonon is about an order of magnitude larger than predicted by calculations in the local density approximation (LDA). This anomalous behavior suggests that many-body effects due to electron-electron interaction are important. Photoemission experiments show a large kink in the hole dispersion at about 70 meV binding energy or less. This suggests a strong coupling to bosons. Natural candidates are phonons, e.g., the (half-)breathing phonon. Photoemission also shows formation of polarons for undoped cuprates, indicating strong electron-phonon coupling for these systems. Starting from the three-band model, we have derived a t-J model with phonons. In the t-J model, Cu d-holes and O p-holes form so-called Zhang-Rice singlets. For a rigid lattice, the large singlet energy (about 5 eV) leads to an uninteresting constant in the total energy. Due to the strong distance-dependence of the hopping integrals and Coulomb integrals, however, displacements of the atoms lead to large changes of the singlet energies. The result is a strong electron-phonon interaction. We find that the coupling to the site energies due to the modulation of the hopping integrals dominates. This coupling explains the anomalous softening of the half-breathing phonon (Electron-Phonon Interaction in the t-J Model

Electron With the discovery of a new class of oxide superconductors, the cobaltates (which become superconducting at a temperature around 5 K), scientists were naturally curious whether they could learn something about their mechanism to shed light upon this problem. "What we've found," says Brookhaven physicist Peter Johnson, "has opened up another twist." As Johnson's group cooled the cobalt-oxide materials, they observed electronlike excitations at temperatures well above the so-called transition temperature where the materials become superconductors. "If we had discovered these before we discovered the cuprates we'd probably think the same electron pairing mechanism was responsible for all superconductivity," Johnson says. Johnson will explore the implications of this work in his talk during the session on "Novel and Complex Oxides IV" on Tuesday, March 23, at 2:42 p.m. in room 511E. This research is funded by the Office of Basic Energy Sciences within the Department of Energy's Office of Science.

Two-Dimensional Fluctuating Superconductivity Scientists at Brookhaven Lab have discovered a state of two-dimensional (2D) fluctuating superconductivity in a high-temperature superconductor with a particular arrangement of electrical charges known as "stripes." The finding was uncovered during studies of directional dependence in the material's electron-transport and magnetic properties. In the 2D plane, the material acts as a superconductor - conducts electricity with no resistance - at a significantly higher temperature than in the 3D state. "The results provide many insights into the interplay between the stripe order and superconductivity, which may shed light on the mechanism underlying high-temperature superconductivity," said Brookhaven physicist Qiang Li, who presented this work at the American Physical Society meeting, March 10-14, 2008. Understanding the mechanism of high-temperature superconductivity is one of the outstanding scientific issues in condensed matter physics, Li said. Understanding this mechanism could lead to new strategies for increasing the superconducting transition temperature of other superconductors to make them more practical for applications such as electrical transmission lines.

Last Updated: 29 August 2007 Overview, Objectives and Strategies The High-Temperature Superconductivity Agreement enables the collaborative assessment of the impact of advances in high-temperature superconductivity on the electric power sector and the Agreement provides a forum for the exchange of information among its members. Advances in superconductivity are being achieved simultaneously in a number of countries and this programme enables Participants to share the cost of evaluating that progress. The Agreement started in 1990, and was most recently extended to 2010. The programme concerns itself with assessing and evaluating the significance and promise of high temperature superconductors for the electric power sector and facilitating the consideration of same. Cooperation among the participants enables these considerations to be more informed, objective and thus enlightening than considerations otherwise available at the national level. The Programme stimulates consideration of issues of mutual interest by holding workshops and publishing reports and proceedings on specific topics including: High Amperage Conductors; Power Quality, Refrigeration for High-Temperature Superconductors, Magnetic Separations, High-Temperature Superconductor use in Generators and Motors; Progress towards Superconducting Magnetic Energy Storage and Flywheel Energy Storage Using superconducting Bearings; Cables; and Fault Current Limiters and Transformers.

Public release date: 11-Jan-2008 E-mail Article Contact: Andrea Bianchi andrea.bianchi@umontreal.ca University of Montreal New understanding for superconductivity at high temperatures University of Montreal physicist and international team share findings in Science An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed. Andrea D. Bianchi, the lead researcher from the Université de Montréal, explains in the January 11 edition of Science magazine what he discovered in an exceptional compound of metals – a combination of cobalt, indium and a rare earth – that loses its resistance when cooled to just a couple of degrees above absolute zero. “This discovery sharpens our understanding of what, literally, holds the world together and brings physicists one step closer to getting a grip on superconductivity at high temperatures. Until now, physicists were going around in circles, so this discovery will help to drive new understanding,” said Prof. Bianchi, who was recruited to UdeM as a Canada Research Chair in Novel Materials for Spintronics last fall and performed his experiments at the Paul Scherrer Institute in Switzerland, in collaboration with scientists from ETH Zurich, the University of Notre Dame, the University of Birmingham, U.K., the Los Alamos National Laboratory and the Brookhaven National Laboratory. Magnetic tornado that grows stronger Using the Swiss Spallation Neutron Source (SINQ), Prof. Bianchi and his team cooled a single-crystal sample of CeCoIn5 down to 50mK above absolute zero and applied a magnetic field nearly high enough to entirely suppress superconductivity. They found that the core of the vortices feature electronic spins that are partly aligned with the magnetic field. This is the first experimental evidence that a theory that describes the properties of superconducting vortices and, for which Abrikosov and Ginzburg received the Nobel Prize in 2003, which does not generally apply in magnetically-induced superconductors.

Links to More Information Super Conductors About Superconductivity How would you like to board a Maglev train and then speed off to your destination at more than 300 miles per hour? The magnets that levitate these trains are an application of superconductivity Metals are good conductors of electric current. That is, they have very low electrical resistance, but this resistance is not zero. A voltage difference is still required to generate the current in the metal, and the metal heats up while the current is flowing. The electrical resistance of an object depends on its temperature and declines slowly as the temperature falls. Early in the last century, however, a Dutch physicist discovered that a sample of mercury, when cooled below a certain temperature close to absolute zero, loses all electrical resistance. When the mercury is in this state, an electric current flows indefinitely, even in the absence of any applied voltage. This effect is called "superconductivity." The table lists the everyday metals that exhibit superconductivity and the temperature below which electrical resistance disappears. These elements require cooling by liquid helium to become superconductors. Such materials are called "low-temperature superconductors."
