Abstract
The ferromagnetic Heusler Ni39+xMn50Sn11−x (x ≤ 2.0) alloys have been developed in tailoring the martensite transition with functional magnetocaloric properties. A single martensite phase of a herringbone nanostructure grows in a specific composition Ni41Mn50Sn9 (x = 2.0) which exhibits large irreversibility in the enthalpy change (ΔH), heat-capacity change (ΔCP), and magnetization (σ) during heating and cooling in the martensite ↔ austenite transition. As large value as ΔHM←A–ΔHM→A = 0.12 J/g has been observed with ΔCP(M←A)–ΔCP(M→A) ~22.5 mJ/kg-K from a DSC thermogram of a broad peak over from 225 K to 375 K. Thermomagnetic curves measured at a low magnetic field B = 5 mT reveal ~58 % lowered σ-value on heating a field cooled sample from a super paramagnetic martensite state at 250 K to a ferromagnetic austenite state with a distinct peak at 320 K. This irreversibility is highly sensitive to the alloy composition. As a result, a small change in the Sn-content ~9.5 at % (x = 1.5) gives reasonably much lowered ΔHM←A–ΔHM→A = 0.1 J/g and ΔCP(M←A)–ΔCP(M→A) = 10 mJ/kg-K in a martensite-austenite composite phase.
