Abstract
Magnetization measurements on a ceramic YBaCuO sample were carried out. TheM(H, T) dependence has demonstrated some peculiarities which we assume are connected withH j1,H j2,H c1 fields. By analyzing the magnetization in the field region betweenH j1 andH j2 within the framework of the critical state model, one obtains the dependence of the intergranular critical current density on field and temperature.
