Фазовые превращения и свойства сплава Гейслера системы Ni–Mn–In

The phase and magnetic transformations in a ferromagnetic alloy of the Ni–Mn–In system are studied using dilatometry, magnetometry, metallography, and scanning electron microscopy. The effect of a magnetic field of varying intensity on the martensitic transformation and magnetic transitions of the Ni$_{47}$Mn$_{42}$In$_{11}$ alloy is found. It is shown that the linear expansion coefficient and magnetization exhibit an anomalous behavior in the region of the magnetostructural transition.
