Chaotic precession of antiferromagnetic domain walls
Chaotic precession of antiferromagnetic domain walls
In contrast with extensive investigations on the translation of domain walls (DWs) in antiferromagnetic (AFM) materials, the precessional motion of an AFM DW is seldom concerned partly because of the lack of an effective driving method. In this Letter, we show that under an alternating spin-polarized current with polarization along …
