Effect of d.c. magnetic field on microwave losses in single and polycrystalline high- Tc superconductors

The investigation of the microwave surface resistance of high- T c single and polycrystalline samples having similar parameters in the presence of trapped flux has been performed. It is shown that the main part of the microwave losses in high- T c ceramics is determined by flux trapped in the grain...

Description
Summary:The investigation of the microwave surface resistance of high- T c single and polycrystalline samples having similar parameters in the presence of trapped flux has been performed. It is shown that the main part of the microwave losses in high- T c ceramics is determined by flux trapped in the grain clusters.
