Abstract

Fe2Mn3Si3-based alloy with minor cubic Heusler Fe2MnSi phase was prepared for the first time via self-propagating high-temperature synthesis. The reaction initiated at 668°C, reaching a maximum of 1115°C, indicating high exothermicity driven by Fe–Mn interaction. Room-temperature magnetic properties showed weak ferromagnetism (coercive force of 42 Oe and and remanent magnetization of 0.20 emu/g), attributed to paramagnetism of Fe2MnSi and impurity-induced disordering in Fe2Mn3Si3.
