• "Magnetic Materials, Fundamentals, Properties, and Applications"
This course is an introduction to the recent developments in the field of magnetic materials and spintronics. Mainly focused on the experimental aspects of the field, it starts from the origin of the magnetism in atoms and ions to various magnetic phase in solids. An introduction to the application of magnetic materials will be discussed in the final sessions. This course is expected to be continued by a course in Nanomagnetism in the next semester. Basic knowledge on quantum physics, thermodynamics and solid state physics is mandatory for the course and it is consisted of the following sections:
