ABSTRACT:
A novel intermetallic superconductor with surprisingly high transition temperature is disclosed. Exemplary of the novel superconductor is material of overall composition Y.sub.1.5 Pd.sub.4.5 B.sub.4. A bulk sample of that composition has T.sub.c (onset) of 22.6K, with about 0.5 volume % of the sample being superconducting.
