EFFECTS OF Sc SUBSTITUTING Y IN YBa2Cu3O7-δ ON THE FLUX PINNING PROPERTIES
Abstract
The effects of Sc in high Tc superconductors are seldom discussed due to the difficulty of Sc embedding into the unit cell. Single phase of Y1-xScxBa2Cu3O7-δ (YSBCO) is obtained with x<0.15. The critical current (Jc) varies with the content of Sc in an oscillating way, which has showed two maximum values at x=0.03 and x=0.10, individually. We here discussed the effect of Sc doping on Jc.
