Magnetization measurements were performed with a SQUID magnetometer on a pressed Ag-sheathed BSCCO (2223) tape. The hysteresis loops, analyzed in the framework of the ''Critical State model'' show clear anomalies. The results are explained invoking granularity of the sample, as confirmed by the analysis of the reverse leg of the magnetization. The irreversibility line, measured in the orientations B//c and B perpendicular to c, is also presented.

Abstract
Magnetization measurements were performed with a SQUID magnetometer on a pressed Ag-sheathed BSCCO (2223) tape. The hysteresis loops, analyzed in the framework of the ''Critical State model'' show clear anomalies. The results are explained invoking granularity of the sample, as confirmed by the analysis of the reverse leg of the magnetization. The irreversibility line, measured in the orientations B//c and B perpendicular to c, is also presented.
