Magnetic Properties of Nd₃Fe_27.7-xNi_xTi_1.3 Compounds

Abstract:

The structure and magnetic properties of the Nd₃Fe_27.7-xNi_xTi_1.3 compounds prepared by arc-melting method have been investigated by means of X-ray diffraction and magnetization measurement. It was found that all the compounds crystallized in Nd₃(Fe, Ti)₂₉-type structure with monoclinic symmetry and A2/m space group in concentration range 0.2 ≤ x ≤ 1.2. The unit cell volume decreased slightly with increasing Ni content. The X-ray diffraction patterns of the magnetically aligned samples showed that all compounds investigated had planar anisotropy. The Spin reorientation phenomena occurred in all the compounds. As the increase of Ni content, the Curie temperature T_C monotonously increased, but the spin reorientation temperature T_sr did not obviously change. The saturation magnetization Ms of the compounds decreased monotonously with increasing Ni content at 5 K, 105 K, 205 K, and 305 K. The anisotropy fields B_a at 5 K, 305 K and anisotropy constant K₂ at 305K appeared as a minimum, but the anisotropy constant K₁ at 305 K appeared as a maximum on x = 0.6.
