Abstract
Studies of microwave absorption at low fields in zero-field-cooled (ZFC) and field-cooled (FC) samples of Hf-doped Y-Ba-Cu-O are presented. Flux trapping during the FC process is clearly demonstrated. Results show that the superconducting glass phase appears in ceramics for fields greater than or equal to Hm (where Hm is the field at which the signal is maximum), where the difference between ZFC and FC signals starts. The results can be explained quite satisfactorily in terms of a percolation description and the superconducting cluster model.
