The possibility to predict the exchange interaction values and Curie temperatures of magnetodielectrics is shown using the superexchange bond model and the specific dependences of the intraatomic exchange integral, the transfer parameters, and the excitation energy of electrons from ligand to cation on a number of electrons in the 3d‐shells of cations. Ability is demonstrated on examples of ferrite‐spinels and perovskites of arbitrary composition.
