Magnetooptics deals with the phenomena arising when light interacts with a material subject to magnetic field, and
thus it represents a powerful tool for investigation of both magnetic ordering and microscopic structure of the
material. This lecture provides a comprehensive overview of theoretical and experimental approaches utilized in
magnetooptics, with a main focus on their practical applications.

This lecture aims to familiarize students both with experimental and theoretical methods used in magnetooptics. In the first part of the course a basic electromagnetic approach to the magnetooptical (MO) effects in a matrix formalism will be presented, together with its application for calculation of the magnetooptical parameters. In the second part of the lecture a microscopic origin of the MO effects will be outlined and various materials for the MO applications will be discussed. The third part of the course will deal with MO experimental techniques. Last update: T_KCHFO (26.03.2014)
