Abstract

We report upon the excellent magnetocaloric effect in melt-extracted DyHoCo medium entropy microwires. The magnetic entropy change (-ΔS_M) reaches a large value of ∼11.2 J kg⁻¹ K⁻¹ for a field change (μ₀ΔH) of 5 T. The large value of -ΔS_M is resulted from the large magnetic moments of Dy and Ho. In addition, the DyHoCo microwires show a good cooling efficiency; RC1, RC2 and RC3 are evaluated to be ∼530 J kg⁻¹, ∼417 J kg⁻¹ and ∼279 J kg⁻¹, respectively, at μ₀ΔH = 5 T. The DyHoCo microwires undergo a second-order paramagnetic-ferromagnetic transition at the Curie temperature of ∼35 K. The excellent magnetocaloric property makes the melt-extracted DyHoCo microwires a promising refrigerant for cryogenic cooling application.
