Growth of Mn₄N film with enhanced perpendicular magnetization on glass substrate using MnO seed layer

Ferrimagnetic Mn₄N films have been prepared on glass substrate by reactive magnetron sputtering with in-situ prepared MnO seed layers. Mn₄N film directly grown on glass substrate is used as a control group to compare. It has been found that the Mn₄N film can grow heteroepitaxial on the MnO layer, the crystallinity and perpendicular magnetic anisotropy are significantly improved by the seed layer. The excellent magnetic properties and simple preparation methods will definitely boost the application potential of Mn₄N film in spintronics devices.
