“…It is noteworthy that in contrast to the usual magnetization behaviour of the R-T intermetallic compound with ferromagnetic coupling between the R and T magnetic moments the magnetization decreases gradually on increasing temperature from low temperature to Curie temperature; the magnetization of Nd 3 Fe 26.8−x Co x V 2.2 compounds increases gradually on increasing the temperature from 4.2 K to around room temperature in a low field of 0.05 T. This phenomenon was reported for Nd 3 Fe 24.5 Cr 4.5 and Sm 3 Fe 24 Cr 5 compounds [17] and was explained as the magnetohistory effect, which can be described based on the presence of narrow Bloch walls [18,19]. The presence of the narrow Bloch walls requires a large ratio of anisotropy energy to exchange energy.…”

Single-phase Nd 3 Fe 26.8−x Co x V 2.2 compounds with Nd 3 (Fe,Ti) 29 -type structure have been synthesized successfully for x = 0-12; and their structures and magnetic properties were investigated by x-ray diffraction and magnetic measurements. The Curie temperature increases drastically with increasing Co content from 500 K for x = 0-847 K for x = 12. All the compounds show a spin reorientation transition as temperature decreases. Spin reorientation temperature T sr shows an increasing tendency with the exception of a minimum at around x = 6. Saturation magnetization increases monotonically with increasing Co content, which can be understood in terms of a rigid band model. The anisotropy field at 5 K decreases with increasing Co content. All the compounds show easy-plane-type anisotropy at room temperature and the series of the compounds is not suitable for permanent materials.

“…6 is depicted the temperature dependence of magnetization of SmNiAl at 100, 1000, 10,000 and 30,000 Oe in the ZFC and FC processes. The ZFC magnetization is lower than the FC one in all applied fields, being the same as usual cases caused by magnetic domains and the motion of domain walls [32]. In the ZFC branch, there are three peaks at or above 1000 Oe, which are the characteristic of antiferromagnetism and suggest three magnetic transitions, i.e., formation of three kinds of antiferromagnetic orderings.…”

“…Among them, some Tb-Al binary alloys have been particularly studied by neutron scattering techniques [4,5,6]. From those studies, it was concluded that TbAl 2 shows ferromagnetism at T C = 105 K [4], TbAl is a non-collinear antiferromagnet with T N = 72 K [5], whilst Tb 3 Al 2 is a ferromagnet with T C = 190 K [6]. On the other hand, studies of magnetic properties of other members of the Tb-Al series indicated an antiferromagnetic behaviour at T N = 21 K and 52 K for TbAl 3 and Tb 2 Al, respectively [1,7,8].…”
