The magnetic field dependence of transport critical current density (Jet(H)) was measured at 77 K for Bil.S4Pbo.34Sr2.03Cal.gCu3.06Oy granular superconductors with Jet(0) of 3814 and 7170 A/era 2. From the initial magnetization curve, the lower critical field (He1) of the grain was evaluated to be a
