Title: Superconductivity and ferromagnetism in Pd doped Y 9Co 7

Abstract

The ferromagnetic superconductor Y 9Co 7 was chemically doped to yield the solid solution Y 9Co 7-xPd x for 0 < x < 0.4. The lattice parameter a does not depend on x, whereas c increases with increasing Pd content up to x = 0.2, the palladium solubility limit. The transition from ferromagnetism (T C = 4.25 K) to superconductivity (T sc = 2.4 K) was observed only for the parent Y 9Co 7 compound. For the lowest tested Pd doping level (x = 0.05), ferromagnetism is enhanced strongly (T C = 9.35 K) and superconductivity is not seen above 1.8 K. Finally, the Curie temperature rapidly increases from 4.25 K to about 10 K for a Pd concentration of x = 0.1 and remains almost unchanged for Y 9Co 6.8Pd 0.2.
