Course Objective

In comparison to their bulk counterparts, thin films and nanoparticles exhibit a number of unusual and interesting phenomena. By properly tuning the film thickness, as well as the nanoparticle size and geometry, it is possible to benefit from the magnetic properties of these structures.

In this course, it is aimed to provide the student with basic scientific knowledge about magnetic thin films and magnetic nanoparticles and to provide a background for advanced research topics.
