متن کاملMagnetic Hysteresis Modelling Based on Magneto-optical Kerr Effect
The paper presents an identification method of the numerical Preisach hysteresis model, based on the digital acquisition and processing of the magnetic microstructure images, which are obtained by time-resolved magneto-optical microscopy. The statistic Preisach function is computed by the superposition of all pixels, allowing to verify the basic assumptions of Preisach hysteresis model from the...
متن کاملGiant magneto-optical Kerr effect and universal Faraday effect in thin-film topological insulators.
Topological insulators can exhibit strong magneto-electric effects when their time-reversal symmetry is broken. In this Letter we consider the magneto-optical Kerr and Faraday effects of a topological insulator thin film weakly exchange coupled to a ferromagnet. We find that its Faraday rotation has a universal value at low frequencies θF=tan(-1)α, where α is the vacuum fine structure constant,...
متن کاملMagneto–optical Kerr Effect in Semi–infinite Inhomogeneous Layered Systems
The contour integration technique applied to calculate the optical conductivity tensor at finite temperatures in the case of inhomogeneous surface layered systems within the framework of the spin– polarized relativistic screened Korringa–Kohn–Rostoker band structure method is extended to arbitrary polarizations of the electric field. It is shown that besides the inter–band contribution, the con...
