Abstract:

The results are given of EPR studies performed in superconducting ceramic YBa2Cu3O7 and Tl2Ba2Ca2Cu3O10 samples and YBa2Cu3O7 single crystals with the surface coated (decorated) by organic radical of diphenil picrilhydrazil (DPH) having a narrow EPR signal. In the superconducting state there is observed an inhomogeneous broadening of EPR signal from DPH due to arising the flux-line lattice. On the basis of experimental data the magnetic field penetration depth lamba0 and behavior lambda(T) are calculated. The last is described satisfactorily by law {[}1 - (T/T(c))4]-1/2. From experiments on single crystal samples the statement that the main contribution into inhomogeneous broadening is given by the flux-line lattice and not by the granular and screening effects is obtained.
