High-entropy oxide Mg0.2Co0.2Fe0.2Ni0.2Zn0.2O was successfully synthesized. Using X-ray diffraction analysis, it was found that the sample has a single-phase composition with the NaCl-type face-centered cubic structure and the lattice constant of 4.22 Å. The sample was studied using Mössbauer spectroscopy at temperatures from 80 K to 295 K. It was determined that the relative content of divalent and trivalent iron ions in the sample is 67% and 33%, respectively. Based on the temperature dependence of the hyperfine magnetic field on 57Fe nuclei, the magnetic transition temperature was determined to be 201 K.
