摘要：

The magnetic anisotropy and the magnetic relaxation between 1 and 10 GHz of ultrathin Ni(1 1 1) films on Re(0 0 0 1) is studied by ferromagnetic resonance in ultrahigh vacuum. For 6-14 monolayers a small-bulk-like anisotropy is measured indicating the nearly complete structural relaxation of Ni into its cubic FCC structure. Around 12 ML a change of sign in the anisotropy reflects the change in surface morphology known from previous STM results. The ferromagnetic resonance linewidth shows a characteristic maximum near the ferro- to paramagnetic phase transition which is caused by the increase of magnetic fluctuations and an enhanced relaxation of the magnetization.
