Introduction to Magnetism

The lecture ''Introduction to Magnetism'' is the regular course on Magnetism for the Master curriculum of the Departement of Physics of ETH Zurich. With respect to the similar lecture course in previous semesters we have decided that we need to insist on the fundamental aspects of magnetism -- the Quantum mechanical aspects on one side and the statistical physics aspects on the other, which are often not comprehensively spelled out in conventional lectures on solid state physics.
