摘要: Abstract The experimentally determined a.c. susceptibility is not explained by the critical surface state or effective conductivity models. A simple quasistatic model, valid in both static and swept d.c. fields, developed which implicitly takes into account contributions to hysteresis. model reasonable agreement with experimental results accord observed magnetization curve. show that flux motion through sensitive sense of applied field change. This available creep models but rectification effects. In view pinning centres region this seems reasonable.
