We have proposed a physical analysis method that combines the Finite-Difference Time-Domain (FDTD) for electromagnetic field analysis with a numerical solver for the Landau–Lifshitz–Gilbert–Slonczewski (LLGS) equation, which describes the magnetization dynamics of antiferromagnets (AFMs). Using this method, we analyzed the response characteristics when a spin-polarized current is injected into an AFM modeled as a cell. Furthermore, although we extended our investigation to AFMs, differences occurred in the responses of the magnetization vectors. In this report, to analyze these differences, we examine the magnetization behavior in the case of two spatially separated AFMs.
