DESCRIPTION:The promise of spin-electronics (spintronics) is that logic pr
 ocessing based on the spin of an electron can be faster and lower power th
 an the conventional charge-based equivalent in semiconductor transistor te
 chnologies.  However\, generating and propagating the necessary spin curre
 nts is not low power because large charge currents are required at device 
 inputs\, which dissipate heat\, limiting circuit efficiency.  The real bre
 akthrough would be the creation of spin-polarised supercurrents in which t
 here is no dissipation.  In 2001\, theory predicted that at a carefully en
 gineered superconductor / ferromagnet interface it would be possible to cr
 eate a source of spin-polarised supercurrents.  In 2010\, our group discov
 ered how to generate such dissipation-free spin-currents and now we are in
 vestigating the fundamental properties of this new superconducting state a
 nd its potential in practical devices. In this talk\, I will provide an ov
 erview of this work on spin-polarised superconductivity.
