摘要

用单色Al - Ka辐射对Y9Co7和纯Y、Co的相关核心能级和价带进行了ESCA实验。还测量了磁化率、交流磁化率和电阻率随温度的变化。得出了一些结论,在Y9Co7中d电子比在金属Co中更强的局域化和在Y9Co7中费米能级上d态密度的增强。

ESCA investigations of a magnetic superconductor Y9Co7
ESCA experiment of the relevant core levels and valence bands of Y9Co7 and pure Y and Co have been performed with monochromatised Al Ka radiation. The magnetisation, AC susceptibility and resistivity were also measured as functions of temperature. Some conclusions were drawn about stronger localisation of the d electrons in Y9Co7 than in metallic Co and an enhanced density of d states at the Fermi level in Y9Co7.
