| contents | Ferrimagnets take the advantages of both ferromagnets and antiferromagnets making them promise for spintronic applications. Here we prepared ferrimagnetic Mn4N thin films with high Curie temperature and investigated the crystalline structure and magnetic properties affected by the Pd buffer layer. We demonstrated that both crystalline quality and perpendicular magnetic anisotropy (PMA) of Mn4N thin films are enhanced significantly due to the relaxation of tensile stress induced by the Pd buffer layer. We also demonstrated a fast spin precession at room temperature, almost 100 GHz, in Mn4N thin films. With the characteristics of high thermal stability, enhanced PMA by buffer layer and fast spin precession, Mn4N thin film is a promising material for spintronic applications. |
