Abstract

We report the preparation and characterization of a melt-processible high-temperature superconductor based on a melt reaction between TbBa//2Cu//3O//7// minus //x and Y//1//. //2 Ba//0//. //8CuO//4// minus //y at 950 degree C. The samples have sharp superconducting transitions above 90K as determined by resistivity and AC susceptibility measurements. X-ray diffraction shows crystal structures nearly identical to those of Y Ba//2Cu//3O//7// minus //x sintered superconductors. The dense void-free melt-processible superconductors have potential for large single crystal growth and for high critical currents with low-cost processing.
