Description
  • We report on the magnetic and thermal properties for the three multicomponent systems TbxDyyRz(Co,Fe)2, (R is Gd, Ho, Er; x + y + z = 1). We show that the Curie temperatures (TC) and order of the phase transition could be controlled by composition. The highest values of magnetocaloric effect (MCE) were observed for the compounds exhibiting the transitions of the first order. Giant volume magnetostriction of 1500–2000 and 500–600 ppm is demonstrated at a field of 10 and 1.2 T, respectively. Structural and magnetic entropy contributions to the total isothermal entropy change are estimated for TbxDyyRzCo2. Regular recurrence and/or change of the physical properties across the varied composition of the compounds allows us to find the materials with desired magnetic characteristics, such as TC, MCE, and magnetostriction, to use them in practice.
