Abstract
The variation in crystallographic and magnetic properties with Dy concentration has been investigated on Y 1−x Dy x Fe 11 Mo and Y 1−x Dy x Fe 11 MoN y compounds in detail. Lattice parameters a, c and saturation magnetization M s at 1.5 K decrease while the Curie temperature T c slightly increases with increasing Dy concentration in Y 1−x Dy x Fe 11 Mo system. At room temperature, all Y 1−x Dy x Fe 11 Mo samples exhibit a uniaxial anisotropy, and the anisotropy field decreases with increasing Dy concentration. Upon nitrogenation, the nitrides Y 1−x Dy x Fe 11 MoN y retain the tetragonal structure symmetry of ThMn 12 type with the addition of an expansion of about 4% on the unit cell volume. The Curie temperature and saturation magnetization at 1.5 K are drastically enhanced by nitrogenation. Unlike the parent alloy, YFe 11 MoN y shows a canted anisotropy at room temperature. But the other Y 1−x Dy x Fe 11 MoN y compounds with x⩾0.2 have a uniaxial anisotropy which becomes stronger with increasing Dy concentration.
