• Iron film deposited on a Mg0(001) surface grows layer by layer and forms an epitax-ial film at room temperature. Low-energy electron diffraction (LEED) I-V curves aremeasured for films of various thicknesses. In comparison with the curves bytheoretical analysis it is found that an iron film grows pseudomorphic and iron atomssit just above oxygen ions at the stage of one mornolayer (1 ML) average thickness.The structure of an iron film is body-centered tetragonal (bct) in the early stage, but itbegins to change to bcc structure at about 10 A average thickness and at the same timea widening of the valence-band electronic state is observed by Auger electron spec-troscopy (AES).iron film, Mg0(001) surface, surface structure, FEED, I-V curve, AES
