Phenomenological theory for twinning-plane superconductivity in YBaSUB2/SUBCuSUB3/SUBOSUB7-x/SUB

摘要

A phenomenological theory for superconductivity in the presence of a periodic array of twinning planes is developed. Various quantities are calculated such as: specific heat, critical fields, Josephson current and pinning forces, due to twinning plates.
