Effects of a constant electric field in the polariton spectrum of a 1D magnetic photonic crystal with antiferromagnetic interlayer exchange

The effect of a constant external electric field was analyzed and the contribution of the volume fractions of magnetic and nonmagnetic phases to the polariton dynamics of a one-dimensional easy-axial fer-romagnet-nonmagnetic dielectric photonic crystal with a magnetic compensation point was determined using the effective medium method.
