“…In [4], the authors studied spontaneous magnetostriction and that induced by an external magnetic field for two multicomponent alloys Tb0.3Dy0.35Ho0.35Co2 and Tb0.8Dy0,1Gd0.1Co2. These alloys demonstrate a high level of magnetostrictive deformations in the area of weak magnetic fields, mainly due to compensation of magnetic anisotropy in their rare earth sublattice [5].…”

“…The structure of intermetallic compounds considered in this work was studied with the methods of X-ray diffractometry. In particular, in [4], X-ray diffraction spectra obtained at various temperatures were processed with a Rietveld full-profile analysis in the Fullprof programming environment.…”

“…Magnetostriction measurements are conducted either with a dilatometer [4], whose operation principle is based upon measuring electrical capacitance changing with the size of the specimen, or by a strain gage (tensometric) method. The scope of an inquiry in all the studies was limited to 300 К.…”

“…Work [4] also studied changes in the value and sign of magnetostriction of Tb0.3Dy0.35Ho0.35Co2 and Tb0.8Dy0.1Gd0.1Co2 specimens depending on temperature and application of external magnetic field. All the stated dependences demonstrate their maximum values at the Curie temperature, including voluminous magnetostriction.…”

This work presents an overview of research results in magnetic and magnetostrictive properties of rare earths-based intermetallic compounds conducted by Russian and foreign researchers. A special attention is paid to multicomponent alloys, as variation in component concentration, temperature and external fields allows for successful influence over the exchange interaction, thus leading to unique phenomena in the area of phase transformations.
