Magnetic Field Dependence of Transport Current and Dissipative Properties of Superconductive Ceramics Y--Ba--Cu--O

Magnetic field dependences were experimentally obtained and analysed of the critical transport current in a bulk polycrystalline sample for various magnetic sample histories. For the same sample dependences of ac losses were experimentally investigated and explained in a periodical oscillating magne...

Description
Summary:Magnetic field dependences were experimentally obtained and analysed of the critical transport current in a bulk polycrystalline sample for various magnetic sample histories. For the same sample dependences of ac losses were experimentally investigated and explained in a periodical oscillating magnetic field on the background field. Graphs. 5 ref.--AA
