The changes in the electronic spectrum and spin magnetic moment on the 3 shell of iron and vanadium ions in cubic solid solutions LaSrFeVO, where 0 ≤ y ≤ 0.15, 0.05 z ≤ 0.35 depending on the composition, were studied using the coherent potential method. The calculated concentration dependencies of the electronic and magnetic properties of non-stoichiometric ferrites LaSrFeO and LaSrFeVO correlate well with the experimental data. It was shown that the LaSrFeVO phases with Fe/Fe, Fe/Fe, V/V and V/V redox transitions in the energy interval Δ ≈ 1.15 eV are of interest for energy storage devices.
