Magneto-optic Kerr effect CCD imaging with polarization modulation technique

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-...

Magnetic properties of ultrathin Co / Ag / Ge ( 1 1 1 ) films studied using surface magneto - optic Kerr effect technique

Co/Ag/Ge (1 1 1) films show an in-plane anisotropy as deposited at 200K. The ferromagnetic inactive layers, formed due to the intermixing of Co and Ge, can be efficiently reduced to zero thickness by introducing 6 monolayer (ML) Ag as a buffer layer. For Co/3ML Ag/Ge (1 1 1) films, the amount of Ag is not enough to separate Co and the Ge substrate. This results in the formation of a 2-monolayer...
