Degree of Sublattice Noncompensation of Antiferromagnet at the Antiferromagnet/Ferromagnet Interface.

A degree of sublattice noncompensation of antiferromagnet (DSNA) can play a crucial role in the designing of a diagonal-like and curvilinear geometry at interfaces of antiferromagnet (AFM) with other magnetic media because of the exchange interaction both between AFM sublattices and with neighboring material. We present a conceptually advanced theory which uses a variable DSNA to describe the behavior of spin waves (SWs) propagation through any designed AFM/FM interface. We propose the boundary conditions for any case of the DSNA. We demonstrate the dependency of transmittance, reflectance and corresponding phase shifts at the interface on the DSNA according to the reasonable SW wavelength.
