Voltage control of interfacial magnetism such as magnetic anisotropy as well as Dzyaloshinskii-Moriya interaction can be employed for operational technology of magnetic random access memory. Since Bi has large spin-orbit interaction, we would like to employ Bi to enhance the voltage controlled magnetic anisotropy in Fe/MgO-based devices. We have previously reported that ultrathin Bi can be epitaxially grown on bcc-Fe (001). In this study, we report magnetic properties of the epitaxial V/Fe/Bi/MgO multilayer by spin-wave spectroscopy.
