Co BASED HEUSLER ALLOY

PROBLEM TO BE SOLVED: To solve the problem that, though a cobalt based Heusler alloy is expected as the candidate of a half metal material (P=1), its spin polarizability measured by a point contact Andreev reflection method (PCAR method) is the degree of 0.6 which is remarkably lower than the value...

Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that, though a cobalt based Heusler alloy is expected as the candidate of a half metal material (P=1), its spin polarizability measured by a point contact Andreev reflection method (PCAR method) is the degree of 0.6 which is remarkably lower than the value (P=1) of half metal in all the alloys, and to provide a Co based Heusler alloy which has a high spin polarizability which has not been obtained heretofore. SOLUTION: The Co based Heusler alloy has compositional formula Co2MnW1-XGaX (wherein, 0
