Type of article: Article

Summary

A simple method for evaluation of the lower limit of intergrain magnetic flux motion viscosity is presented. It is also shown that in the experiment the energy loss in an alternating magnetic field in a granular YBCO superconductor, prepared by the standard sintering method, is determined by thermally assisted magnetic flux flow into superconducting grains, and does not depend on the intergrain space.
