Summary

The results are given of EPR studies performed in superconducting ceramic YBCO and TCBCO samples and YBCO single crystals with the surface coated (decorated) by organic radical of diphenyl 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 and behaviour are calculated. 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.
