摘要：

YBaCuO films with c- or a-axis texture were prepared by laser deposition and sputtering. From rotational hysteresis losses critical current densities and pinning forces are calculated. The torque relaxation gives activation energies in the range of 0.21 to 0.37 eV. Characteristic differences of critical current densities and activation energies are related to the film microstructure.
