“…The ratio of rare-earth elements in the studied compounds differs from the calculated one; nevertheless, we already observe a significant magnetization decreasing. The magnetization compensation in the compounds (Sm,Tb)Fe2 diluted with yttrium was observed earlier [25,26]. Thermomagnetic analysis in the temperature range 80-800 K allows to obtain the Curie temperatures of the studied compounds.…”

A comprehensive study of the structure and phase composition, magnetostrictive and magnetic properties of the (Sm0.5R0.5)Fe2 (R = Gd, Tb) compounds was performed. The effect of partial replacement of samarium by gadolinium and terbium on the microstructure of the surface, the temperature of phase transitions, the magnitude of magnetostrictive deformations and magnetization was studied. Using atomic force and magnetic force microscopy, the surface topology at the micro and nanoscale was established, and information on the magnetic domain structure at room temperature was obtained.

“…In the (Tb1-хYх)0.8Sm0.2Fe2 system, the yttrium and samarium are introduced into the rare-earth terbium sublattice, which affect the properties and the main magnetic characteristics of the TbFe2 compound depending on the substitution parameter х. Earlier, in stationary magnetic fields up to 14 kOe, there were discovered a number of phenomena, such as the phenomenon of spin reorientation, the phenomenon of magnetic compensation, and the inversion of the sign of the magnetostriction constants [8][9][10] depending on the parameter x. The main magnetic characteristics of alloys in the indicated fields are given in Table The investigation of alloy magnetization (Tb1-хYх)0.8Sm0.2Fe2 in static fields up to 14 T was also carried out at a temperature of 4.2 K.

The paper presents the results of studying the alloy magnetization of the multicomponent system (Tb1−xYx)0.8Sm0.2Fe2. The substitution parameter in this system takes the following values: x = 0, 0.2, 0.4, 0.6, 0.8, 1. In the system, the atoms of magnetic terbium were replaced by atoms of weakly magnetic samarium and nonmagnetic yttrium. X-ray diffraction analysis determined the structure and lattice constant for all compositions. Phase analysis was carried out. It is known that by varying the concentration of components, temperature, and external fields, one can successfully influence the magnitude of exchange interactions leading to one or another type of magnetic ordering in the rare-earth intermetallic metals. Therefore, the main goal in this work was to investigate the possibility of observing the magnetic phase transition – ferrimagnetism – ferromagnetism - in the alloys of the system from the curves of the field dependence of magnetization in strong fields up to 60 T. The studies were carried out at the liquid helium boiling point. The main magnetic characteristics of the alloys of this system were determined, such as saturation magnetization σs, magnetic moment per formula unit μ and magnetic moment μFe on iron atoms. Their dependences on the concentration of yttrium were established. The possible values of the magnetic moment per formula unit in the case of ferromagnetic ordering of these alloys were calculated theoretically. It was concluded that these fields are insufficient to observe the ferrimagnetism – ferromagnetism phase transition.
