Magnetic enhancement and nitriding process of Fe atomic layers on Si 111-7×7-CH3OH surface

Aim to greatly enhance the magnetic performance, room temperature nitriding experiments were implemented on existing linear Fe clusters. Firstly, dissociation of CH3OH adsorption process was deducted in detail, which laid a good foundation for better use surface quasi-potential. Further solve coming problems like weak linearity and low effect, atomic layers deposition are confirmed as key NH3 (at temperature). Specifically, higher layer contacted by NH3, weaker influence With introduction Ar, cluster structure could be precisely controlled at single layer, result efficiency. Combining with performance result, density residual magnetization is improved from 1.5E?0.5 emu 7.0E?0.5 emu, forming an obvious structure.
