Spin waves at the ferromagnetic-antiferromagnetic interface
Pestana, E., Mata, G. J., Pantoja, N.

Abstract

We investigate the magnon modes in the neighbourhood of the interface between a ferromagnet and an antiferromagnet. The system is one-dimensional and it is characterized by three parameters -JF, JA, and J0 which describe the exchange couplings in the ferromagnet, the antiferromagnet, and across the interface itself. We study the nature of the interface magnons as a function of these parameters.
