The magnetic properties of single-crystal Ba0.6K0.4BiO3 were studied. The results show that this isotropic superconductor (cubic structure with Tc ≈ 32 K) exhibits irreversibility and relaxation properties similar to those observed in the layered, high temperature superconductors. For fields above 0.1 T, an irreversibility line Birr = Birr (0) (1 - t)n with n = 3 2 and Birr (0) = 20 T is observed. The comparison among several superconducting systems with different anisotropies suggests that the irreversibility line is unlikely to be the melting line for the YBa2Cu3O7-δ.
