Abstract:

The magnetic properties of GdBa2Cu3O7-X and YBa2Cu3O7-X have been studied in low applied magnetic field by using pelleted sample. The magnetic behavior may be explained by the occurrence of a spin-glass state due to a granular superconductor. The model assumes superconducting grains which are small compared to the penetration depth, and these are coupled into closed loops. Cooling in zero-field, followed by the application of a field at a fixed temperature produces a metastable state resulting in frustration and spin-glass behavior.
