    Field Dependence of the Transport Critical Current in Polycrystalline TlBa2Ca2Cu3Oz Films

    Large critical currents with a relatively weak magnetic field dependence are obtained in thick films of TlBa2Ca2Cu3Oz. Transport measurements indicate Jc > 105 A/cm2 at 77K, zero field, and Jc>104 at 60K in a 2T ...
