We report measurements of the superconducting and magnetic behaviors of GdBa2Cu3Ox. Superconductivity sets in at 95 K with large Meissner effect. This compound exhibits Curie-Weiss behavior above Tc with the free-ion effective moments of 7.94μB, and with the Weiss temperature of about - 10±5 K. Moreover, long-range magnetic ordering was observed below 2.2 K by specific-heat measurement without any distinct change of ac susceptibility. This result implies that the superconductivity coexists with the magnetic order below 2.2 K.
