Magneto Optical Kerr Effect

ABSTRACTIn-situ scanning tunneling microscopy (STM). magneto-optical Kerr effect (MOKE) and Kerr microscopy are used to investigate the relations between structure, morphology, and magnetism in low-temperature (LT) grown Fe/Cu(100) films. At the spin reorientation thickness of ≈ 3.8 monolayers (ML) Fe/Cu(100) the coexistence of in-plane and out-of-plane magnetized domains is observed. For Fe thicknesses between 3.8 and 6 ML Fe/Cu(100). an irreversible spin reorientation from in-plane to out-of-plane can be induced by annealing up to 420 K. Annealing of LT-grown Fe/Cu(100) films is proposed to provide smooth surfaces for Cu/Fe/Cu(100) sandwich preparations.

Magneto Optical Kerr Effect

ABSTRACTThe nonlinear Magneto-optical Kerr-effect (NMOKE) has been proven to be an ultrafast spectroscopie probe of the magnetic and electronic properties of ferromagnetic surfaces. Extending our previous theory we calculate the linear and nonlinear Magneto-optical Kerr-spectra of Fe. The results for the nonlinear Kerr spectra are compared with recent experiments on a Fe (110) surface. We derive and discuss general features of the nonlinear Kerr-effect, especially the details of its dependence on exchange interaction and Fermi-level crossings in the Stoner picture and beyond, frequency, and spin-orbit interaction. Furthermore we demonstrate how various electronic material properties, such as d-band width, s-d hybridization or band narrowing due to electronic correlations or caused by geometry (reduced coordination number in thin films), can be extracted from the spectra. As an example, we compare the linear and nonlinear Kerr-spectra of Fe to those of Ni. The extension of our theory to the Kerr spectra of thin magnetic films films as well as of hidden magnetic interfaces occurring in sandwiches and multilayers is discussed.
