The effects of Yb-doping on the critical current density(Jc) and the critical temperature(Tc) in YBa2Cu3O7-δ(YBCO) were investigated.Rietveld refinements of X-ray diffraction showed that Yb3+ ions had partly substitu...
Effects of oxygen plasma on improvement of superconductivity in y-123 were studied here. At room temperature quenched samples were treated with oxygen plasma produced by discharging oxygen gas. As quenched y-123 was t...
