theory_of_'high_temperature'_superconductivity MP21k New clues in search for theory of superconductivity 3 June 2004 A novel magnetic excitation discovered in two different cuprate superconductors could lead physicists towards a theory of high-temperature superconductivity. Two separate teams of physicists have used the new MAPS spectrometer at the ISIS neutron source in the UK to observe the excitation. Theorists have been trying to explain high-temperature superconductivity, without success, since it was discovered in 1986. http://physicsweb.org/article/news/8/6/2 040606 ... . ... 040607 ...
