Gate-Controllable Magneto-optic Kerr Effect in Layered Collinear Antiferromagnets

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...

Development of a Surface Magneto-Optic Kerr Effect Magnetometer

This thesis presents the development and optimization of a surface magneto-optic Kerr effect (SMOKE) magnetometer. Our magnetometer is explained in terms of its three major parts: mechanical setup, electrical connections, and LabVIEW programming. An upgrade of the electrical system is shown to double the available applied field. Studies of the deviation angle and incident polarization direction...

MAGNETO-OPTIC KERR EFFECT AND ELECTRONIC STRUCTURE OF Fe1/3TaS2

Fel13TaS2 is a ferromagnetic intercalation compound. Band structure calculations show various deviations from the rigid band model. We suggest that the measured Kerr spectrum is due to four transitions with paramagnetic line shape from states situated near the Fermi level to higher lying Ta-states.

Single-qubit Quantum Gates using Magneto-optic Kerr Effect

We propose the use of magneto-optic Kerr effect (MOKE) to realize single-qubit quantum gates. We consider longitudinal and polar MOKE in reflection geometry in which the magnetic field is parallel to both the plane of incidence and surface of the film. MOKE couples incident TE and TM polarized photons and the Hamiltonian that represents this interaction is isomorphic to that of a canonical two-...
