Spectroscopic studies of Co2MnSi Heusler alloy
Král, Daniel ; Veis, Martin (advisor) ; Uhlířová, Klára (referee)
In the last years Heusler compounds showed properties that make them suitable materials for spintronic applications. Their magnetic and optical proper- ties are strongly dependent on their structural order, making it an important mat- ter of research. Co2MnSi can exhibit diferent types of lattices, i.e. B2 and L21, while B2 transits to L21 by the process of annealing. In this work we present a stu- dy of optical and magneto-optical properties of Co2MnSi thin films with different annealing temperatures. Spectroscopic ellipsometry as well as magneto-optical spectroscopy in linear and quadratic configurations were used as experimental techniques. Our goal was to determine wheather the magneto-optical meassure- ments are more accurate tools for lattice transitions studies than spectroscopic ellipsometry.
