| Popis: | Microwave absorption studies of the new high-Tc superconducting systems Tl-Ba-Ca-Cu-O (Tc( rho =0)=118 K) and Bi-Ca-Sr-Cu-O (Tc( rho =0)=84 K) were conducted using an X-band EPR spectrometer. The main features observed were (i) a sharp change in the leakage current at Tc; (ii) intense low-field ( |
