Bulk Anisotropy

Ferromagnetic resonance (FMR) measurements on Co films of thicknesses 10–100 Å grown on GaAs (110) and Au (111) substrates have been made as a function of dc magnetic field orientation in a plane perpendicular to the film. Experimental data were fitted by writing the energy density expression including uniaxial perpendicular anisotropy terms up to second order and bulk anisotropy terms. Co films grown on Au (111) substrates show consistently a higher uniaxial perpendicular anisotropy compared to those grown on GaAs (110) for the same thickness of Co. This is attributed to stress induced anisotropy due to a lattice mismatch between Au (111) and Co layers.

Stable Domain

The ground state magnetization of nanowires built of ferromagnetic crystallites is considered taking into account the magnetostatic interaction. The criterion of formation of domains is found. The thickness of a domain wall is calculated analytically and the results are compared with the numerical simulations. We show that when the exchange coupling between crystallites is absent its role is played by magnetostatics that ensures the existence of stable domain structure. The direction of the induced anisotropy axis is shown to be determined by the shape of crystallites.

Reflectance Measurements

In this work we present a detailed study showing the importance of the Kubelka-Munk (KM) correction in the analysis of diffuse reflectivity measurements to characterize spin crossover compounds. Combined reflectance and magnetic susceptibility measurements are carried out as a function of temperature or time to highlight the conditions under which this correction becomes critical. In particular, we investigate the influence of the color contrast between the two spin states on the reflectance measurements. Interestingly, the samples’ contrast seems to play an important role on the spin-like domain structure as suggested by the symmetry of the FORC diagrams. These latest results are discussed within the framework of Classical Preisach model (CPM).
