Abstract Fe atoms were deposited on Si(1 1 1)-7 × 7 restructured surface, which had been covered by CH3OH molecules. A newly formed surface is stabilized by a quasi-potential made by breaking, and adsorbed atoms or molecules can be stabilized by forming “quasi-compounds”. Then, aim to greatly enhance the magnetic properties of the memory units, nitriding experiments were implemented on the existing Fe compounds. With the in-situ observation of STM, a series of Fe3N structures make up the newly emerged iron-nitride compounds, showing good linear characteristics. By adjusting the concentration, this study further explored its formation process and compounds models.
