The critical state model predicts reversible dependence on the d.c. field in disagreement with observed irreversibility which is explained by interaction between Abrikosov vortices in grains and Josephson vortices in weak links.Range of Applicability for the Critical State Model and the Interaction between the Abrikosov and Josephson Vorticestext::journal::journal article::research article
