Abstract

Measurements of the irreversible magnetization, ac susceptibility and electrical resistivity of Bi₂Sr₂Ca_1-xEr_x(Cu_1-yM _y)₂O_8+d bulk are reported. Low concentrations of the doping elements increase the pinning force density and shift the magnetic irreversibility line towards higher fields. The intergranular critical current density was determined from ac susceptibility data by varying the field amplitude H_ac in the range from 0.4 to 1000 A/m and from the irreversible part of magnetization using Bean's model. The results were discussed in terms of SIS- and SNS-type models for granular superconductors.
