Magnetic properties of pseudo-binary compounds Y(Fe,Al) 2 and Y(Co,Al) 2

Abstract

The electronic structures of binary compounds YM 2 (M = Fe and Co) and ordered ternary compounds Y(M 0.75Al 0.25) 2 and Y(Fe 0.25Al 0.75) 2 with the cubic Laves phase structure are calculated by the self-consistent APW method. The anomalous magnetic properties observed in Y(Fe,Al) 2 and Y(Co,Al) 2 are discussed using the calculated results of the density-of-states curve.
