Abstract
We prepared Ag-sheathed Nd system tape by the compression molding powder-in-tube method. Ag sheathed tapes of Nd system superconductors were studied for sample with nominal composition of NdBa2Cu3Oy(Nd123). The critical current density of sample apparently depended on the thickness of the tape and temperature gradient, and increased markedly with decreasing the tape thickness. The maximum value of the critical current density of sample reached 2.0×105 A/cm2 at 6.7 K in zero magnetic field for a tape with 0.3 mm thickness and 1.1×104A/cm2 at 77K in zero magnetic field.
