"High Temperature" Superconductors
University of Michigan February 22, 2006 Physics 441-442 Advanced Physics Laboratory "High Temperature" Superconductors 1. Introduction In this experiment you will investigate some of the properties of a superconductor that becomes superconducting in liquid nitrogen.
High Temperature Superconductors (HTS)
When the superconductor disk is cooled with LN2, the magnet actually rises (levitates) to a position above the disk from a resting position on top of the superconductor disk.
High Temperature Superconductivity
The first superconductor was found in 1911 and through 1973 the transition temperatures that were found were all in the 4.2 - 23 K range. This required the use of liquid helium to attain these temperatures.
The critical current of superconductors: an historical review
The superconductor now shows an induced resistance, the value of which approaches that of the normal state, r n, as the magnetic induction rises to B c 2, ...

Quantum Computing with Superconducting Devices
What is a Superconductor? "A Superconductor has ZERO electrical resistance BELOW a certain critical temperature. Once set in motion, a persistent electric current will flow in the superconducting loop FOREVER without any power loss."
A new Y-based HTSC with Tc above 100K
Y124 compound has one CuO double chain instead of the single chain in the Y123 compound, and becomes superconductor at 80 K [5] . Y247 is another compound based on Ythatbecomesa superconductor at 40K [6] .
Superconducting Materials – A Topical Overview
Since the first discovery of an organic superconductor in 1980 [14] remarkable critical temperatures T c > 10 K have been achieved [15]. However, the origin of superconductivity has turned out to be certainly far from the suggested excitonic mechanism.
