... resistance in the superconducting state , Meissner and Ochsenfeld ( 1933 ) discovered that a superconductor is a perfect diamagnet . A superconductor excludes a mag- netic field except in a small penetration region ( ~ 500 Å ) near the ...

... resistance in the superconducting state , we first note that the Cooper pairs in a superconductor have zero total spin and therefore are bosons , which undergo a Bose - Einstein condensation . This means large numbers of Cooper pairs ...
