Abstract
A method for enhancing the flux pinning of a YBCO superconductor by substituting minute quantities of rare earth elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) or other deleterious elements (Sc, etc.) for Y in YBCO thin films is described. The method of the present invention enables enhanced flux pinning of the material while not significantly increasing the cost of the HIS material and can be used in all HTS deposition methods since it is not process dependent.
