The paper presents results of study of the dependence of the Ni-Mn-In film’s composition on the annealing parameters, data of scanning electron microscopy and energy dispersive analysis (EDX spectroscopy). The Influence of annealing of a film in vacuum on the chemical composition is shown. The content of manganese and indium decreases sharply with a rise in temperature up to 900 °C, and in a heating time up to 2 hours. The ferromagnetic Curie point in the investigated Ni-Mn-In films is observed. A decrease of the width of the ferromagnet-paramagnet transition results in the improvement of the crystallinity of the sample after annealing.
