Magneto Optical Kerr Effect

This paper deals with a new and exciting problem: the possible onset of magnetism in 4d-transition-metals adsorbed on a noble-metal substrate. For Pd on Ag(001), the monolayer is found non-magnetic whereas, for thicknesses of the film comprised between 3 and 5, a magnetic moment is present. For Rh on Ag(001), the monolayer is found strongly magnetic whereas, for thicknesses of the film greater than one monolayer, no magnetism is present. Our results for Pd on Ag(001) are in agreement with recent Surface-Magneto-Optical-Kerr effect and Electron-Capture-Spectroscopy displaying no magnetism for the monolayer but ferromagnetism for thicker slabs. Experimentally, Rh on Ag(001) is not a layer by layer growth: interdiffusion and severe islanding are present. Therefore, a more complex calculation, taking into account these growth conditions have to be performed in order to compare with "real systems".

Magneto Optical Kerr Effect

ABSTRACTNonlinear magneto-optical Kerr effect in Gd-containing Langmuir-Blodgett superstructures is studied by second harmonic generation (SHG) interferometry. The intensity of the regular magneto-induced second harmonic (SH) is found to be by a factor of about 2 larger than the intensity of the regular SH component of a non-magnetic origin. The phase shift between the magneto-induced and non-magnetic contributions to the nonlinear polarization is about 46° The intensity of the magnetization-independent hyper-Rayleigh scattering (HRS) is by two orders larger than that of mnagneto-induced HRS.

The exsolution of magnetite from a substituted Yttrium Iron Garnet, containing an iron excess may lead to a transitional event. This event is characterized hy the formation of a transitional zone at the center of which the magnetite nucleates (Fig.1). Since there is a contrast between the matrix and these zones and since selected area diffraction does not show any difference between those zones and the matrix in the reciprocal lattice, it is of interest to analyze the structure of the transitional zones.By using simultaneously different techniques in electron microscopy, (oscillating crystal method microdiffraction and X-ray microanalysis)one may resolve the ionic process corresponding to the transitional event and image this event subsequently by high resolution technique.
