Magnetization loop and critical current of porous Bi-based HTS

The magnetization of porous Bi 1.8Pb 0.3Sr 2Ca 2Cu 3O x has been investigated. The experimental magnetization hysteretic loops of M( H) were described in the frames of Val’kov–Khrustalev model developed for type II granular superconductors.
