摘要：

Magnetic properties and remanent magnetization have been measured on epitaxial YBa2Cu3O7 thin films deposited by laser ablation on (100) SrTiO3 substrates. Hysteresis loops are reported at different temperatures. The large values of the remanent magnetizations correspond to critical currents Jc larger then 107 A cm-2 at 10 K, circulating around the whole sample. The field dependence of the magnetization, related to the field dependence of Jc, is analyzed. The remanent magnetization, studied as a function of maximum applied field, are described by power laws. Finally, pinning energies in the range of 100 meV are evaluated from the thermal dependence of Mr. © 1990.
