Lecturers & Examiners: Prof. em. Dr. Danilo Pescia
VVZ CR n/a

Last Updated: 2026-02-05 15:14:48

Abstract

Atomic paramagnetism and diamagnetism, intra- and inter-atomic exchange, RKKY exchange interaction, Stoner model, the mean field approximation, spin waves, mean field approximation, competing interactions, spin orbit coupling, domains, domain walls.

Objective

This lecture is intended as an introduction to Magnetism and forms the basis for the lecture on magnetism by R. Allenspach of IBM Zurich in FS08, which will treat the applications of magnetism to modern technology. Here is a preliminary and not complete list of subjects which will be dealth with in the present lecture: Non-existence of magnetism in classical physics, quantum mechanical origin of paramagnetism and diamagnetism in atoms, quantum mechanical treatment of intra- and inter-atomic exchange, the RKKY exchange interaction, the Stoner model of band ferromagnetism, the mean field approximation of the Heisenberg Hamiltonian, spin waves, competition between quantum mechanical exchange and dipolar interaction, the role of spin orbit coupling, (domains, domain walls).
