Abstract
We herein fabricated the (Dy0.25Ho0.25Er0.25Tm0.25)2Cu2In high-entropy (HE) compounds and systematically determined its structural, magnetic, and magnetocaloric properties. The (Dy0.25Ho0.25Er0.25Tm0.25)2Cu2In HE compound was found to crystalize in a tetragonal Mo2B2Fe type structure (P4/mbm space group) and undergoes typical second order type magnetic transition. Large MCE and prominent cryogenic magnetocaloric performances were observed in (Dy0.25Ho0.25Er0.25Tm0.25)2Cu2In HE compound. The evaluated values of magnetic entropy change and refrigerant capacity of (Dy0.25Ho0.25Er0.25Tm0.25)2Cu2In HE compound under magnetic field change of 0–7 T are 17.1 J/kgK and 398.0 J/kg which are comparable with the reported candidate materials for cryogenic magnetic cooling, making the present (Dy0.25Ho0.25Er0.25Tm0.25)2Cu2In HE compound also considerable for practical applications.
