“…Its variation is also increasing with the Ir concentration till the cancelation of spin and orbital moments [34]. The increase in the magnetic moment of Zr and the decrease in the magnetic moment of Ir are due to the phenomenon of magnetic moment compensation that leads to an average interaction between different spins [35]. The Ferromagnetic state is the lowest in energy consideration.…”

This paper presents the structural, magnetic properties, and spin moment cancelation phenomenon of the zirconium oxide with a gradual change of zirconium for Iridium. The density functional theory (DFT) is shown to be a key feature of magnetic properties of solid materials treatment. It is shown that a small adjustment of the spin moment (less than 6%) is allowed. The Zr1-xIrxO2 crystal structure deformation leads to a magnetic compensation that occurs at x=0.06. Spin and orbital moments behaviors are discussed. The stability of the alloy compounds is confirmed by energy calculations. The material presents ferromagnetic stability and an indirect exchange coupling with a hybridization effect that permitted the evolution from a non-magnetic to a host material with magnetic properties. The Ir orbitals are set at the Fermi level and are spin polarized which indicates a half metallic behavior then makes the material a good candidate for spintronics’ applications.

“…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.
