Abstract
We present our observations of hysteretic magnetization or c-axis oriented thick (1-2 mu m) YBCO films in parallel fields. For other orientation of th e field, the magnetization is mainly due to the c-axis component (M(c)sin t heta) becauseof a large aspect ratio of the observations at low fields (les s than or equal to 100mT) did not follow such behavior. Moreover, the in-pl ane magnetization is affected by an artifact introduced during the depositi on of such thick films. We discuss our results in the framework of Bean's m odel after removing the artifact.
