Abstract:This bachelor's thesis deals with magneto-optic effects with special aim for magneto-optic Kerr effect. Presented description allows us to quantify magneto-optical observables on the basis of measuring the light intensity after the reflection from sample surface. Consequently, we use a simple physical model to unriddle the origin of the optical anisotropy induced by the external magnetic field. In the part, that deals with the design of an aparatus for measuring magneto-optical Kerr effect in longitudinal conformation, we provide necessary information to define a device capable of measuring magneto-optic observables in micro/nano scale. Last chapter i aimed to the achieved results on the thin Co films and on magnetic vortices with lateral dimensions of 1 μm.
Magnetic properties of thin films and microstructures, Kerr effect, magneto-optics, Jones formalism, magnetic vortices, longitudinal Kerr effect.
