Abstract
Magnetic anisotropy evolution of ultrathin Fe films grown on Pt(001)single-crystal surface is investigated by UHV in situ surfacemagneto-optical Kerr effect (SMOKE) measurement. After annealing at~600 K, the magnetic anisotropy of Fe film switches from in-planeto perpendicular at low coverage, leading to a spin reorientationtransition (SRT). Meanwhile, in the range of 3–4 monolayer (ML)thickness, the coercivity of the Fe polar hysteresis loop decreasesdramatically. Further scanning tunnelling microscopy (STM) and lowenergy electron diffraction (LEED) investigation correlates themagnetic properties with the film structures. We attribute this SRT tothe formation of Fe–Pt ordered alloy.
