arXiv:2401.07171 · doi:10.21468/SciPostPhysLectNotes.85
Abstract
These lecture notes from the 2023 Summer "School Principles and Applications of Symmetry in Magnetism" introduce the reader to the classical field theory of ferromagnets and antiferromagnets.
Edits in response to referee comments. A section added to describe a topological contribution to the total spin of an antiferromagnetic chain
