✦ Synopsis

The critical current density Jc of YBazCu30 x epitaxial film as a function of the angle 0 between magnetic field and ab-plane with H _1_ I and temperature was measured in various magnetic fields. Maxima of Jc were observed near 0 ° and 90 °, respectively, with that for the latter higher than that for the former. A deviation of Jc(0 °) peaks from 0 ° and the asymmetry of Jc(O) with respect to 0 = 90 ° are observed in the field below 0.5 T. It is found for the first time that n is a function of magnetic field in the relation Jc cc (1 -t)'.
