Magnetic properties of Y(Co1−xFex)10Si2 compounds

Abstract The magnetic properties of Y(Co 1− x Fe x ) 10 Si 2 ( x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) compounds have been studied. All compounds crystallize in ThMn 12 type structures. The lattice parameters a and c increase with increasing iron content, while the Curie temperature has a maximum at about x = 0.6. The easy magnetization direction at room temperature changes from basal plane to the c -axis at about x = 0.2. The anisotropy field obtained by the SPD technique reaches a maximum at x = 1.0, with values of 2.1 T at room temperature and 2.6 T at 77 K respectively.
