Correlation between the Dzyaloshinskii-Moriya interaction and spin-mixing conductance at an antiferromagnet/ferromagnet interface
Correlation between the Dzyaloshinskii-Moriya interaction and spin-mixing conductance at an antiferromagnet/ferromagnet interface
The rich interaction phenomena at antiferromagnet (AFM)/ferromagnet (FM) interfaces are key ingredients in AFM spintronics, where many underlying mechanisms remain unclear. Here we report on a correlation observed between the interfacial Dzyaloshinskii-Moriya interaction (DMI) ${D}_{\mathrm{S}}$ and effective spin-mixing conductance ${g}_{\mathrm{eff}}^{\ensuremath{\uparrow}\ensuremath{\downarrow}}$ at the IrMn/CoFeB interface. Both ${D}_{\mathrm{S}}$ and ${g}_{\mathrm{eff}}^{\ensuremath{\uparrow}\ensuremath{\downarrow}}$ are quantitatively …
