Critical currents in YBaCuO ceramics

Abstract

Magnetization measurements on a ceramic YBaCuO sample were carried out. TheM(H, T) dependence has demonstrated some peculiarities which we assume are connected withHj1,Hj2,Hc1 fields. By analyzing the magnetization in the field region betweenHj1 andHj2 within the framework of the critical state model, one obtains the dependence of the intergranular critical current density on field and temperature.
