Abstract

We have investigated the effect of Ta₂O₅ addition on the superconducting properties of REBa₂Cu₃O_y (RE = Er, Sm and Eu: REBCO) prepared by a powder-sintering method. T_c(zero) values showed no degradation up to 1.0 wt.% Ta₂O₅ addition for ErBCO samples. EuBCO and SmBCO samples showed the increase in T_c(zero) from 89 K to 94 K by the addition of 1 wt.% Ta₂O₅, and 80 K to 94 K by the addition of 2 wt.% Ta₂O₅, respectively. J_c values at B = 0.5 T increased by two times the pure samples for ErBCO with 1.0 wt.% addition, four times for EuBCO with 1.5 wt.% addition, and 33 times for SmBCO with 1.0 wt.% addition. The formation of REBa₂TaO₆ was observed for the Ta₂O₅-added REBCO samples.
