Correlation of anomalous magnetic properties and mechanical treatment of Bi.sub.2./sub.Sr.sub.2./sub.Ca.sub.2./sub.Cu.sub.3./sub.O.sub.10./sub. silver-sheathed tapes

Due to granular character of the tapes, the total magnetic moment is composed of two additive contributions of intra- and intergranular moments. We pressed our samples in a controlled way and observed evolution of the critical current density.

Measurements of induced critical currents in silver-sheathed Bi.sub.2Sr./sub.2Ca.sub.2Cu./sub.3O.sub.10 tapes will the aim to investigate the anomaly of intergranular currents. We gradually destroyed the inter-grain links by imposing and increasing uniaxial stress along the tape normal, and observed the corresponding evolution of the magnetic hysteresis loop shape.
