From: Simulations of magnetization reversal in FM/AFM bilayers with THz frequency pulses
Magnetization reversal using a THz pulse for a permalloy thickness of 6 unit cells for different coupling strengths between FM and AFM. (a) \(0.5 \times 10^{-21}\) J, (b) \(1.0 \times 10^{-21}\) J, (c) \(2.0 \times 10^{-21}\) J, and (d) \(5.0 \times 10^{-21}\) J. Turqoise and yellow are regions of 90\(^{\circ }\) and 180\(^{\circ }\) switching respectively.
