Researchers at Cambridge University, UK, say they have discovered that lanthanum-strontium-copper-oxygen ([La.sub.2]SrCu[O.sub.4]) appears to demonstrate certain traits of superconductivity at near room temperature.
Professor Christos Panagopoulos and his co-researchers report that when some of the lanthanum atoms in [La.sub.2]Cu[O.sub.4] are replaced with strontium atoms, the material conducts electricity without resistance up to about 40 K, but that even at 290 K, it appears to show some aspects of the superconducting state.
In their recent experiments, the Cambridge researchers first placed a sample in a low magnetic field. They then cooled it, ...
