DESCRIPTION:Currents flowing in circuits containing ferromagnets transport
  spin as well as charge\; this is the fundamental origin of effects such a
 s giant magnetoresistance (GMR). In contrast\, the superconducting state i
 s created by the pairing of electrons with antiparallel spins\; this means
  that a supercurrent transports charge but not spin. Until very recently t
 his would have made the idea of superconducting spin electronics completel
 y paradoxical. The possibility that the alternative triplet pairing state 
 could be induced in ferromagnets had been theoretically predicted and conv
 incing evidence for long-range supercurrents in ferromagnets has now been 
 obtained by several groups\, working on different materials systems. \nBec
 ause triplet supercurrents are expected to be spin polarised\, form the st
 arting point for a programme aiming to merge the exciting fields of superc
 onductivity and spintronics. This talk describes the developments which ha
 ve led to this point and the current research taking place within the Mate
 rials Department.\n
