Thickness dependence and magnetocrystalline anisotropy of the x-ray transverse magneto-optical Kerr effect at theCo2pedges of ultrathin Co films on W(110)

The transverse magneto-optical Kerr effect (T-MOKE) in the soft X-ray regime is used to investigate the magnetic properties of ultrathin epitaxial Fe(110) films and thermally created epitaxial Fe islands on W(110). The measurements have been carried out at the Fe 2p core levels with tunable, linearly polarized synchrotron radiation. Besides the chemical selectivity T-MOKE at core levels is characterized by a much larger sensitivity compared to the visible regime. We have analyzed the transition from thin films to a three-dimensional island system at a thickness of 4 ML and the magnetic behavior when increasing the iron coverage to 8 ML. The Fe island system is characterized by a rotation of the easy magnetization axis in this coverage regime.

Magneto Optical Kerr Effect

AbstractA brief discussion of the resonant magnetic scattering process is given. Results from recent studies of thin Fe films and Fe/Gd multilayers are used as examples to demonstrate the information can be obtained and the unique features of this technique: large resonant enhancement, sensitivity to magnitization, elemental specificity, and tunability of the penetration depth. Comparison is made with related techniques: magneto-optical Kerr effect, Faraday effect, and magnetic circular dichroism.

Short Heating

We have investigated the effects of oxygen exposure on Co films grown on Pd(111) single crystal using magneto-optical Kerr effect and X-ray photoemission spectroscopy. Upon 300-langmuir oxygen exposure, the cobalt films are oxidized as CoO and a small amount of Co 3 O 4, the latter being reduced to CoO on short heating at temperatures higher than 700 K. The ferromagnetic properties disappear by oxygen exposure. However, part of CoO decomposes into cobalt and oxygen on further annealing, and the ferromagnetic property reappears.
