Abstract
Neutron diffraction studies have been made on the intermetallic compounds, ErFe2Ni, ErFe1.5Ni1.5, and ErFeNi2, to determine the effect of the nonmagnetic Ni atoms on the three magnetic phases of ErFe3. Diffraction patterns above the Curie temperature show that Ni atoms almost exclusively occupy the h1 sites. At room temperature, a nearly basal plane ferrimagnetic arrangement of magnetic moments results whereas at 4.2 K, a noncollinear structure is observed, in contrast to the uniaxial collinear structure obtained for ErFe3. The results are explained on the basis of the competitive local anisotropies and the change in exchange interactions of Er‐Fe upon substitution of Ni.This publication has 7 references indexed in Scilit:
