ESR method was used for directely measuring the response of the superconductor to an external field Hc1 < Hext < Hc2. The surface effective susceptibility below TC was determined from ESR measurements of local field intensities obtained with two DPPH paramagnetic markers located to the cylindrical surface of Y:123 superconductor. Our results were explained in relation with the field distribution at the surface and by different grain structures. The appearance of two resolved ESR lines at TC = 90.2 K were correlated by the AC magnetic susceptibility measurements. |
