| Zielgruppen: |
This lecture course is primarily for first year master students but als for last year bachelor students in physics in the specialization on solid states physics.
|
| Voraussetzungen: |
You should have taken part in the solid state physics course (5th semester bachelor),
a participation in the course Magnetism I offered in the winter term is very helpful but not a general prerequisite.
