Summary

Magnetization-induced optical surface second harmonic generation (SHG) revealed one-monolayer oscillations in iron (Fe) film growth. Minima in magnetic contributions were observed at half-filled monolayers, indicating oscillatory surface magnetism.

Area of Science:

  • Surface science
  • Magnetism
  • Optics

Background:

  • Understanding surface magnetism is crucial for advanced electronic devices.
  • Layer-by-layer growth with surfactants offers precise control over magnetic thin films.
  • Optical techniques like second harmonic generation (SHG) provide sensitive probes of surface magnetic properties.

Purpose of the Study:

  • To investigate the oscillatory surface magnetism during layer-by-layer iron (Fe) growth on an oxygen-covered Fe(001) surface.
  • To utilize magnetization-induced optical second harmonic generation (SHG) in a longitudinal geometry for this study.
  • To correlate observed magnetic oscillations with the surfactant effect of oxygen.

Main Methods:

  • Employing magnetization-induced optical surface second harmonic generation (SHG) in a longitudinal geometry.

  • Studying the p(1 x 1)O/Fe(001) surface during layer-by-layer Fe growth.
  • Analyzing one-monolayer oscillations in the SHG signal and magnetic contributions.

    • Main Results:

    • Observed considerable one-monolayer oscillations in surface magnetism.
    • Detected minima in magnetization-induced contributions to the second-order dielectric susceptibility at half-filled monolayers.
    • Confirmed consistent results using both purely magnetic SHG yield and magnetization dependence of the overall SHG signal.

    Conclusions:

    • The observed oscillatory surface magnetism is consistent with oxygen-induced relaxation effects.
    • Surface Fe islands and their interaction with surfactant oxygen drive the magnetic oscillations.
    • SHG is a powerful tool for probing dynamic surface magnetism during thin film growth.
