Dozent Krimmel A.
Dauer 3 SWS
Studiensemester 6
Schein Ja (6 LP)
Termin Termin nach Vereinbarung, 403/Süd
Beginn 23.04.09
Inhalt On the basis of Magnetism I - magnetic moments, magnetic
interactions, susceptibility, anisotropies, domains and
magneto-transport - magnetic ordering processes and
excitations will be discussed. As a key experimental method
for the study of magnetism on a microscopic scale, neurton
scattering will be introduced.

1. Magnetic phase transitions
2. Magnetic structures
3. Neutron diffraction and magnetic structure determination
4. Form factor and magnetization densities
5. Disordered spin systems, spin glasses
6. Neutron spectroscopy
7. Spin waves
8. Crystal field excitations
9. Current research on quantum magnetism
