Polariton dynamics of a bounded weak ferromagnetic in an external DC electric field normal to the interface

With a bounded easy-plane weakly ferromagnetic crystal magnetized tangentially to its surface taken as an example, it is shown that the external DC electric field (collinear simultaneously both with the easy magnetic axis and with the normal to the interface) can lead to the formation of multiple anomalies due to the quadratic magnetooptical interaction under the conditions of propagation of a volume TM or TE wave through the interface between magnetic and nonmagnetic media.
