Abstract: The scattering of exchange spin waves caused by the interface between antiferromagnetically ordered magnetic media is studied. It is shown that, in contrast to the case of uniaxial magnets, when the scattered wave is evanescent, in this case, emission of a propagated wave is possible, the amplitude of which is determined by the difference between the biaxial anisotropy constants.

Keywords: reflection and transmission, exchange spin waves, evanescent waves, precession chirality, ferromagnets with broken axial symmetry.
