Abstract

The ternary Ni-Mn-Sn alloys are embryonic energy materials for swapping heat in the martensite ↔ austenite phase change is useful for many applications. Amongst the functionalities of these alloys, magnetostriction is drawing considerable attention mess which finds its application in sensors, actuators, and many more. The present work investigates the linear magnetostriction (DL/L), volume magnetostriction (DV/V), and magnetization (M) of Ag-substituted Ni41−xAgxMn50Sn9 (x ≤ 2.0) ferromagnetic Heusler alloys. It is found that the forced volume magnetostriction DV/V and bulk modulus K, are inversely related. For the smaller value of magnetic fields, the martensite phase magnetostriction is higher than compared of the austenite phase. The magnitude of the forced magnetostriction varies directly with the valence electron concentration per atom (e/a) value and is reflected in the electron energy, which is responsible for the lattice softening of the alloys in the martensite phase.
