Magnetic properties of the Y1-xLaxCo4B (x=0 to 1) pseudoternary compounds: High and low field studies

Abstract

The YCo4B compound is known to crystalline in the CeCo4B structure with an average Co magnetic moment of 0.7?B which is much smaller than the Co moment of 1.6?B in YCo5. Previously, we have shown that the basal-plane anisotropy of Co in YCo4B changes into easy-axis with increasing temperature (around 150K) or by substituting of La by Y.
