Popis: Highly a-plane-oriented Mn3Sn thin films were grown on m-plane sapphire substrates with low-temperature grown Mn3+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 Mn3+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.
