Abstract
We investigated the crystalline direction dependent Dzyaloshinskii–Moriya interaction (DMI) in single crystal CoFeB(211)/Pt(110) films utilizing the Brillouin light scattering technique. The in-plane magnetic anisotropy and the DMI coefficient show a clear 1/tCFB relation. The quantified DMI strength is −2.5 pJ/m along Pt [001] and −1.2 pJ/m along Pt [11¯0] with a large anisotropy ratio of 2.1. Such a strong anisotropy of DMI is attributed to the C2v crystal symmetry at the CoFeB/Pt(110) interface. Our results provide a route toward designing topological magnetic textures by tailoring the DMI strength along the specific crystal orientation in ferromagnet/Pt(110) systems.
