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