The effect of Ni 3+ ions on the intergranular T p temperature of the imaginary peaks of the ac susceptibility has been studied for a (Bi,Pb):2223 superconductor. The linear dependence of T p as a function of ac field amplitude agree with Muller critical state model. The Ni 3+ ions induced an increase of intergranular pinning force density. J cJ (T) dependence near T c agrees with the assumption of SNS intergrain junctions.

Pinning Force Density

The in plane critical current density jc (B, Θ, T) of dc-sputtered YBa 2 Cu 3 O 7-films and YBa 2 Cu 3 O 7/ PrBa 2 Cu 3 O 7-superlattices was measured in dependence of the angle Θ between the magnetic field [Formula: see text] and the [Formula: see text]-axis of the films in two orientations: 1. The current direction is parallel to the axis of rotation (i.e. [Formula: see text] always). 2. The current flows perpendicular to the axis of rotation (i. e. [Formula: see text]). For low temperatures we do not find any difference between the two current orientations, and the critical current density [Formula: see text] behaves like jc (B cos Θ, 0°). For higher temperatures the two cases differ from each other for Θ near to the maxima in jc at 90° and 270° for the YBa 2 Cu 3 O 7-films whereas for YBa 2 Cu 3 O 7/ PrBa 2 Cu 3 O 7-superlattices we hardly find any change for both experimental setups. We compare the behaviour of the experimental results for the two orientations for the YBa 2 Cu 3 O 7-films and YBa 2 Cu 3 O 7/ PrBa 2 Cu 3 O 7-superlattices and discuss the temperature dependence of the intrinsic pinning force density.
