Abstract The superexchange interaction parameter for the next‐nearest neighbouring pair of magnetic ions in EuO, connected by the 180° exchange interaction has been calculated according to the method of configuration interaction. The effect of the non‐homogeneous potential created by the crystal ions in the region of the chosen complex “metal—ligand‐metal” is taken into account. Satisfactory agreement with experimental data is obtained.
