| 中文摘要 | The scanning tunneling microscopy, low energy electron diffraction, and surface magneto-optic Kerr effect are used to investigate the morphology, structure, and magnetism of ultrathin Fe films on a Pt(100) surface. At room temperature, the deposited Fe atoms exchange sites with the Pt atoms of the substrate, and then grow in a quasi layer-by-layer mode. The Fe films show in-plane anisotropy for all coverages (up to 7 ML). Annealing at 600 K switches the easy magnetization axis from in-plane to perpendicular when the thickness is smaller than 5.2 ML. The coercivity increases gradually to its maximum at 3.3 ML and then decreases abruptly, accompanied with a surface structure transition from (1x1) to c(2x2). These results demonstrate the formation of Fe-Pt L1(0) and L1(2) chemically ordered alloys and a phase transition between them. The atom exchange process is found to play a key role in the alloy formation at significantly reduced growth temperature. |
