Title Stress-induced Curie temperature increase in the Fe64Ni36 invar alloy
Abstract Structural and magnetic changes on invar Fe64Ni36 alloy (TC = 500 K) produced by mechanical milling followed by heating up to 1073 K, were investigated by neutron diffraction, magnetization measurements, X-ray diffraction under high pressures and X-ray absorption at both Fe and Ni K-edges. We argue that the strain induced in the Fe64Ni36 material after this treatment mainly affects the Fe sites due to the magnetovolume coupling, the most notorious feature being the increase of the Curie temperature (ΔTC = 70 K).
