Abstract
The preliminary results of the investigation of magnetic properties of a novel low-density superconducting material Bi1.8Pb0.3Sr2Ca2Cu3Ox with a low density and microfoam structure are presented. The temperature, magnetic field, and time dependences of magnetization M have been measured. The experimental hysteresis loops M(H) are well described in the framework of the Val’kov-Khrustalev theory developed for type II granular superconductors.
