In this study, the thermal expansion of Hf1-xTaxFe2 compounds was successfully regulated by adjusting the Ta concentration. The study focused on the magnetocaloric properties, the influence of hydrostatic pressure on the antiferromagnetic-ferromagnetic transition, and magnetostriction in low magnetic fields.
In this study, the thermal expansion of Hf1-xTaxFe2 (x = 0.10, 0.13, 0.15) compounds by adjusting the Ta concentration was successfully regulated. The magnetocaloric properties, hydrostatic pressure affecting the antiferromagnetic-ferromagnetic transition, and magnetostriction in the low magnetic field were studied. The Delta S-M values of 3.3 J center dot(kg center dot K)(-1) and 3.6 J center dot(kg center dot K)(-1) were obtained under magnetic fields of 10 kOe and 15 kOe in the Hf0.85Ta0.15Fe2, respectively. In the antiferromagnetic-ferromagnetic state transformation process under hydrostatic pressure up to 0.8 GPa, the state temperature does not decrease in a strictly linear manner. Outstanding magnetostrictive properties of 0.12% were obtained at a magnetic field of 10 kOe. This kind of alloy is supposed to be controlled under hydrostatic pressure to obtain good magnetic refrigeration performance and magnetostrictive properties.
