Abstract

Highly a-plane-oriented Mn₃Sn thin films were grown on m-plane sapphire substrates with low-temperature grown Mn_3+xSn buffer layers by sputtering deposition technique, and their crystallinity and magnetic properties were investigated by X-ray diffraction and SQUID magnetometer, respectively. The crystallographic orientations of Mn₃Sn domains are found to be sensitively influenced by substrate temperature, thickness and composition ratio of Mn_3+αSn buffer layer. The highly a-plane-oriented Mn₃Sn film shows slightly different magnetization behavior from randomly oriented Mn₃Sn film, while the saturation magnetization Ms and coercivity of the highly a-plane-oriented Mn₃Sn film are corresponding to that of single crystal bulk.
