UX3 (X=Si, Ge, Sn and Pb) compounds with the cubic crystal structure are interesting in relation with the lattice constant and the electronic state of 5f electrons. We measured the high-field magnetization of USn3 and UPb3 grown by the self-flux method. The broad metamagnetic transition was observed in a heavy fermion paramagnetic compound USn3 at about 30 T, which is similar to the metamagnetism of UPt 3. On the other hand, the sharp metamagnetic transitions were observed in an antiferromagnetic compound UPb3.
