摘要：

The magnetic structure of MnF2 is determined by the neutron diffraction method in the metastable orthorhombic phase grown in the form of thin (∼1 μm) film on a CaF2 buffer layer by the molecular beam epitaxy method. The magnetic moments of Mn++ form a simple two-sublattice antiferromagnetic structure and are directed along the c crystallographic axis parallel to the film plane. Using the temperature dependence of magnetic reflections, a Néel temperature of 67.19(7) K and a critical index of 0.50(2), which corresponds to the mean field approximation, are determined.
