Аннотация
TbCo2Mnx (x ≤ 1) alloys were synthesized and their crystal structure, heat capacity, magnetic and magnetocaloric properties were studied. Single-phase compounds with the MgCu2-type structure were formed at х < 0.4. In alloys with х > 0.4, additional phases with the PuNi3- and Th6Mn23-type structures form. It was shown that there is a substantial increase in the Curie temperature and magnetic moment of 3d‑metal sublattice of the nonstoichiometric compounds when compared to those of the TbCo2 binary compound. The magnetocaloric effect of single- and multiphase alloys were estimated based on magnetic and heat capacity measurements.
