From: Vortex dynamics and frequency splitting in vertically coupled nanomagnets

Simulated absorption spectrum as a function of HDC for a single BD is shown in (a) and for a coupled system with single-domain configuration of the SD is shown in (b). Spectra in (c) and (d) are for the cases with both SD and BD in vortex configuration, but SD with two different chiralities. Fields HRF and HDC are orthogonal to each other.
