Abstract
The intergranular properties of (Bi 1.6Pb 0.4)(Sr 1.8Ba 0.2)(Ca 1- x Er x ) 2Cu 3O y ceramics, with x = 0.00; 0.002; 0.005; 0.010; 0.015; 0.020, were studied by using electrical resistivity and ac susceptibility measurements at zero dc magnetic field. The intergranular critical current density was determined from ac susceptibility data by varying the field amplitude H ac in the range from 0.1 Oe to 20 Oe. The results were discussed in terms of SIS-and SNS-type models for granular superconductors. The analysis of the temperature dependencies of the intergranular current densities suggests that the superconducting grains are connected by normal metal interfaces.
