    A brief overview of recent superconductivity research at NIST is presented. Emphasis is placed on the new high-temperature oxide superconductors, though mention is made of important work on low-temperature superconductors, and a few historical notes are included. NIST research covers a wide range of interests.

High-temperature superconductors are operatively defined as materials that behave as superconductors at temperatures above nearly °C. This is in fact the lowest temperature reachable by liquid nitrogen, one of the simplest coolants in cryogenics.

All superconducting materials known at ordinary pressures currently work far below ambient temperatures and therefore require cooling. The majority of high.

High-temperature superconductors are used in experimental apparatus, and they are actively being researched, particularly in thin film applications. Figure A graph of resistivity versus temperature for a superconductor shows a sharp transition to zero at the critical temperature T c.

Superconductivity - Superconductivity - Magnetic and electromagnetic properties of superconductors: One of the ways in which a superconductor can be forced into the normal state is by applying a magnetic field.

The weakest magnetic field that will cause this transition is called the critical field (Hc) if the sample is in the form of a long, thin cylinder or ellipsoid and the field is oriented. Type 2 superconductors are not particularly good conductors at room temperature, the transition to a superconductor state is more gradual than Type 1 superconductors.

The mechanism and physical basis for this change in state is not, at present, fully understood. Type 2 superconductors are typically metallic compounds and alloys. Low Temperature Superconductivity. LTS stands for “low temperature superconductor,” which typically refers to the Nb-based alloy (most commonly Nbwt.%Ti) and A15 (Nb3Sn and Nb3Al) superconductors in use prior to the discovery of “high temperature” oxide superconductors in Superconductivity, complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature.

This temperature, called the transition temperature, varies for different materials but generally is below 20 K (− °C). The use of superconductors in magnets is limited by the fact that strong magnetic fields above a certain critical value.

Then, in the s, the field changed again with the discovery of unconventional, or high-temperature, superconductivity. “High temperature” is still very cold: the highest temperature for superconductivity achieved was °C for hydrogen sulphide at extremely high pressures.

For normal pressures, °C is near the upper limit.

Cuprate superconductors can have much higher critical temperatures: YBa 2 Cu 3 O 7, one of the first cuprate superconductors to be discovered, has a critical temperature above 90 K, and mercury-based cuprates have been found with critical temperatures in excess of K.

The explanation for these high critical temperatures remains unknown. Audio Books & Poetry Community Audio Computers, Technology and Science Music, Arts & Culture News & Public Affairs Non-English Audio Spirituality & Religion.
