Abstract

We present our observations of hysteretic magnetization of c-axis oriented thick (1-2 /spl mu/m) YBCO films in parallel fields. For other orientations of the field, the magnetization is reported to be mainly due to the c-axis component (M/sub c/sin/spl theta/) because of a large aspect ratio of the film. But our observations at low fields (/spl les/100 mT) did not follow such behavior. Moreover, the in-plane magnetization is affected by an artifact introduced during the deposition of such thick films. We discuss our results in the framework of Bean´s model after removing the artifact.
