چکیده انگلیسی
A consequence of Fe/Ni substitution in the intermetallics Dy(Fe0.7âxNixCo0.3)2 was tested in this paper. Fe57 Mössbauer effect measurements for the intermetallic system were carried out at 4.2Â K. The obtained hyperfine interaction data are presented. The magnetic hyperfine field as well as the Curie temperature is strongly reduced with a composition parameter x. Band structure calculations using the Full-Potential Linearized Augmented Plane Waves (FLAPW) method were performed. The experimentally determined magnetic hyperfine field correlates linearly with the weighted magnetic moment calculated per transition metal atom and correlates linearly with the average splitting energy between 3d subbands. The Curie temperature changes in an approximate linear fashion with the squared magnetic hyperfine field or with the calculated squared splitting energy between 3d subbands.
