Magnetism and superconductivity

Students will be introduced to magnetism and superconductivity, that are collective phenomena which cannot be described by a one-electron model.

During the course lectures about the experimental aspects and standard models for the description of magnetism and superconductivity will be given. The developments in magnetism research and magnetic materials associated with spin-based electronics or “spintronics” will be presented.

About 2/3 of the time will be devoted to magnetism and 1/3 to superconductivity.

Solid state physics, Statistical mechanics
