Internal magnetic fields in the high-temperature superconductor YBa2 Cu3 O7−δ from muon spin rotation experiments
Zeitschrift für Physik B Condensed Matter(1988)
摘要
Muon spin rotation (μSR) measurements of the internal magnetic fields in sintered YBa2Cu3O7−δ samples are reported. Pronounced differences between field-cooled (FC) and zero-field-cooled (ZFC) μSR signals, hysteresis effects and flux trapping are observed. The μSR results are compared with the results of macroscopic experiments (susceptibility, magnetization, resistivity) and with predictions obtained from models of weakly-coupled superconducting regions.
