DEPTH-DEPENDENCE OF MAGNETIZATION AT A FERROMAGNET EDGE UNDER THE INTERFACIAL DZYALOSHINSKII-MORIYA INTERACTION Kaiya, Yuki 00402553 本多, 周太 Honda, Syuta 本多 Honda 周太 Syuta 00293671 伊藤, 博介 Itoh, Hiroyoshi 伊藤 Itoh 博介 Hiroyoshi Ohsawa, Tomokatsu 関西大学 Kansai University The interfacial Dzyaloshinskii-Moriya interaction (I-DMI) occurs in a ferromagnetic wire on a heavy metal. Magnetic moments (MMs) at the edge of the wire are forcibly canted by the I-DMI. The influence of the canting MM at the wire edge on the wire interior is unclear. Here, we theoretically investigate the MMs under the I-DMI. The effect of the canting of MMs at the edge of the interior is shown to increase with a smaller exchange energy and a larger perpendicular anisotropy. A cosine of the cant angle of the MMs decreases exponentially with distance from the edge.
