The tensor of an effective three-photon vertex has been calculated in the one-loop approximation for a medium with non-zero chemical potential. The tensor properties at various photon wavelengths and frequencies have been analyzed. The case of photon scattering by a magnetic field has been studied in detail. Possible applications of the results obtained have been discussed.
