Formation of ultrathin ferromagnetic layers of Fe3Si and Co3Si on silicon studied by photoelectron spectroscopy

摘要

Ultrathin magnetic films of transition metal silicides are perspective for spintronics. In this work we have studied formation of Fe3Si and Co3Si films on Si(100)2×1 by the solidphase epitaxy. The experiments were performed in ultra-high vacuum using photoelectron spectroscopy with synchrotron radiation. Correlations are found out between changes of the phase composition of synthesized films and their magnetic properties.
