Propagation of electromagnetic waves on the lateral surface of a ferrite/semiconductor superlattice at quantum hall-effect conditions - Abstract

The principal result of this work is the existence of coupled magnon-plasmo n surface polaritons, i.e., nonradiative spin-electromagnetic surface waves on the lateral surface of a superlattice that consists of the alternating layers of GaAs-AlGaAs quantum well system and ferromagnetic insulator. Disp ersion relations for the waves are considered at quantum Hall-effect condit ions when a static quantizing magnetic field is perpendicular to the quantu m well plane.
