Fully Relativistic Calculations of Magneto-Optical Kerr Effect

Enhancement of the Magneto-Optical Kerr Effect in One- Dimensional Magnetophotonic Crystals with Adjustable Spatial Configuration

We studied magnetophotonic crystals (MPCs) with introduced magneticdefect layer sandwiched between magnetic and dielectric Bragg mirrors. Thesemagnetophotonic crystals have excellent capabilities to enhance reflection and Kerrrotation simultaneously. By adjusting spatial configuration such as repetition numbersof Bragg mirrors and thickness of magnetic defect layer, we a...

A mirror based polar magneto-optical Kerr effect spectroscopy arrangement.

An arrangement is described for performing magneto-optical Kerr effect (MOKE) spectroscopy in polar geometry with a conventional C-frame or H-frame type electromagnet. It uses an additional mirror which eliminates the need for an electromagnet pole piece with an axial hole and allows for easy switching between polar MOKE geometry and longitudinal or transverse MOKE geometries. A theoretical ana...

Magnetic 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...

Magneto–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...
