Flux Pinning in Superconductors

Superconductivity is now a considerable focus of attention as one of the te- nologies which can prevent environmental destruction by allowing energy to be used with high e?ciency. The possibility of practical applications of sup- conductivitydependsonthemaximumcurrentdensitywhichsuperconductors can carry, the value of losses which superconductors consume, the maximum magnetic ?eld strength in whic...
