CIC01: VECTOR MAGNETOMETRY USING SPECTROSCOPIC MAGNETO-OPTICAL ELLIPSOMETRY
The goal of this Master project is to improve our-state-of-the-art generalized magneto-optical ellipsometer (GME) to allow for spectroscopic measurements and associated characterization capabilities. With such methodological advances, the instrument will have the potential to allow for very precise magneto-optical magnetometry measurements, such as:
(i) depth-resolved magnetometry and
(ii) spectroscopic materials characterization
The project will consist of two parts. In the first part, an existing GME set-up will be reconfigured with a tunable laser to facilitate spectroscopic measurements. Once the system is operational, measurements on magnetic thin film, multilayer, and nano-structure samples (also produced in our labs) will be made to explore the performance levels that can be achieved with the new characterization capabilities that this unique experimental tool offers. This work will include modifications of the experimental set-up and control software to run these novel experiments (LabView programming platform).
In the second part, the experimental results will be analyzed so that quantitative data of the dielectric tensor for different films and materials can be extracted, as well as 3-dimensional vector magnetometry and depth-resolved magnetometry demonstrated, which would represent a very significant methodological advance. This part will include data analysis programming, the use of commercial analysis software and will furthermore benefit from a good understanding of electromagnetism, optics, solid-state physics, and ferromagnetism.
