Dzyaloshinskii-Moriya Interaction across an Antiferromagnet-Ferromagnet Interface
Dzyaloshinskii-Moriya Interaction across an Antiferromagnet-Ferromagnet Interface
The antiferromagnet- (AFM-)ferromagnet (FM) interfaces are of central importance in recently developed pure electric or ultrafast control of FM spins, where the underlying mechanisms remain unresolved. Here we report the direct observation of an Dzyaloshinskii-Moriya interaction (DMI) across the AFM-FM interface of IrMn/CoFeB thin films. The interfacial DMI is quantitatively …
