Magnetic anisotropy and first-order magnetization processes in Sm(Fe1-xCox)10M2 (M= Ti, Si) compounds
No full textThe Sm(Fe1−xCox)10.8Ti1.2 and Sm(Fe1−xCox)10Si2 compounds with tetragonal ThMn12 structure were studied by using the SPD technique in order to investigate temperature and composition behavior of both magnetocrystalline anisotropy and First-Order Magnetization Process (FOMP). The substitution of Co for Fe affects the magnetic properties in the following manner: (1) It enhances the Curie temperature, in a way which is slightly different for the Ti and Si systems. (2) It produces a rapid decrease of the overall axial anisotropy, leading to a change of the sign of the anisotropy, that is to easy plane systems. This effect is quantitatively different for the two systems; furthermore, a comparison with Y(Fe1−xCox)10.8Ti1.2 gives indications for a strong indirect influence of Co on the Sm anisotropy. (3) It decreases both the HCR values and the onset temperatures of the type II FOMP

Magnetic Properties of some Rhombohedral RE-Co Compounds
No full textThe magnetic properties and the magnetocrystalline anisotropy of the rhombohedral RECo3, RE2Co7 and RE5Co19 systems (RE = Y, Nd) have been studied. It has been evidenced that the magnetic phenomenology is qualitatively the same in the different phases. The variation in composition only has a quantitative influence
Magnetocrystalline anisotropy of the 3d sublattice in the cubic intermetallic system Zr6Co23-xMx (M= Fe, Ni)
No full textThe magnetocrystalline anisotropy behavior of the 3d sublattice was studied in the face‐centered‐cubic system Zr6Co23−xMx (M=Fe,Ni). A remarkably high anisotropy field was required to saturate the magnetization along both the [100] and [110] hard directions. The values found are, respectively, HA=43 kOe and HA=33 kOe at 293 K for Zr6Co23. The partial substitution of Co with Ni results in a substantial increase of the anisotropy while saturation magnetization and Curie temperature decrease linearly. On the contrary, the partial substitution with Fe gives rise to a decrease of HA and to an increase of both σs and Tc. The 10th power law does not apply to the functional temperature dependence of the resulting anisotropy in this system
Phenomenological analysis of the magnetocrystalline anisotropy of the Co sublattice in some rhombohedral and hexagonal intermetallic structures derived from the CaCu5 unit cell
No full textA comparative study of the saturation magnetization, Curie temperature, and magnetocrystalline anisotropy in several rhombohedral and hexagonal Y‐Co compounds was done. The considered phases YCo3, Y2Co7, Y5Co19 (rhombohedrals), YCo5+z, and Y2Co17 (hexagonals) are all derived from the hexagonal CaCu5 unit. The variation of the magnetic properties in the different compounds was found to be strongly correlated to the cobalt content. In particular the Co sublattice anisotropy varies linearly with the Co content in the phases, while it seems to be not affected by structural changes (rhombohedral‐hexagonal). The highest anisotropy of Co was found in YCo5, every modification of the CaCu5 cell resulting in a weakening of the overall axial anisotropy. An evaluation of the strength of the Co anisotropy in the 2c, 3g, and dumbbell sites was done using a phenomenological model
