内容摘要：
Antiterromagnetc (AfM) materials exhibit characteristics such as ultrabigh frequency, highspeed, and resistance to magnetie field interference, and are expected to play an important rolein next-generation spintronic devices. The strong AFM exchange coupling between sublatticesmakes their structure more complex and their precession frequency much higher than those offerromagnetic materials, Traditional micromagnetic simulation technigues are difficult toaccurately describe the AFM coupling between neighboring atoms in AFMs. Therefore, spindynamies simulation techniques based on atomic scale and lattice structures are required. In thistalk,we will introduce our recent studies in synthetic antiferromagnets (SAFs)[l] andantiferromagnetic crystals: including the THz excitation of collinear antiferromagnetic MnF, [2]or non-collinear antiferromagnetic Mn,Pt [3]; the spin wave chirality reversal characteristics inantiferrimagnetie GdFe [4] and 2D Van de Waals Crl3 [5], ete.
