Abstract

Magnetic, magnetocaloric, and magnetoelastic properties of TbxDyyRz(Co,Fe)2 (R = Ho, Er; x + y + z = 1) single-phase alloys prepared by arc melting were investigated. The high-purity samples with various compositions were used for the study. In the vicinity of the magnetic phase transition, an abrupt change of the magnetization, a large magnetocaloric effect and a maxima of the volume magnetostriction were observed for the compounds studied. Obtained results of MCE in (Tb,Dy)Co2 agree well with available theoretical calculations.
