✦ Synopsis

A new model is developed to describe the physics of a strong magnetic field H influence on the high-To metal ceramic critical current Jc. The point is that in the most general case the Jc(H) value is determined by the magnitude of a surface current j.f induced in the granules. The basic idea of the model is that the surface current density 38f is the sum of two components j.f=jm+jg. In the Meissner state jm is a diamagnetic (equilibrium) surface shielding current. In the mixed state 3g is induced intragrain current whose sign depends on themagnetic history.

The hysteretic behavior of critical current j C (H) and magneto-resistance R(H) of composites Y-Ba-Cu-O + CuO have been studied and presented. The composites represent the network of tunnel-type Josephson junctions where copper oxide acts as a material forming barriers between superconducting (YBCO)
