Time-Domain Analysis of Antiferromagnetic Spin Dynamics and Electromagnetic Wave Interaction

Antiferromagnets(AFM), recently attracting attention, have small angular momentum and can operate at high speeds because their magnetization is canceled out by paired magnetization vectors.This property makes them suitable for compact oscillators that operate at room temperature and pressure, which are expected to be used in next-generation communications [1][2][3][4].However, experimental research into these materials, especially considering the effects of electromagnetic fields on AFM, is costly and time-consuming.Therefore, numerical simulations are essential for efficiently analyzing their properties.
