I guess this could lead to the ultimate spintronics BUT only if room temperature superconductivity is ever realized.
just one thing puzzles me about this piece: it calls the cooper pairs that have their two electrons spinning in opposite ways to each other “spin-singlet Cooper pairs” and it calls the cooper pairs that have their two electrons spinning in opposite ways to each other “spin-triplet Cooper pairs” but what are they referring to by the words singlet and triplet here in this context? -I mean, single and triple what exactly? -because I don't see any “triple” anything in the diagram for “spin-singlet Cooper pairs”!
