Formål: |
The course gives an introduction to the theory of magnetism in materials and to experimental methods to study or utilize magnetic materials. |
Indhold: |
This course is an introduction to the field of magnetism in condensed
matter. The student is introduced to the one-body and many-body problems
of magnetism and to simple mean-field and reciprocal space techniques for
a solution of the many-body problems. Furthermore, the students is
introduced to a selection of experimental techniques, which are currently
used in research projects. The physical basis of the techniques and
typical data are discussed; the course does not contain laboratory work(/exercises).
The course gives an introduction to the theory of magnetism and magnetic
materials, as well as to the relevant experimental techniques which are
used by research groups in the Copenhagen area. There will be emphasis on
current research. The course will comprise the topics: Magnetic moments in
solids, magnetic interactions, magnetic order, antiferromagnetism,
magnetic excitations, nuclear magnetism, magnetic nanoparticles, magnetic
minerals, bulk magnetic techniques, NMR, Mossbauer spectroscopy,
and magnetic neutron scattering |
Målbeskrivelse: |
The student should be able to
- describe how and why materials have magnetic moments
- describe how and why magnetic moments in materials interact
- calculate the magnetic response of a magnetic material to
an external magnetic field
- describe and visualize the different types of magnetically ordered
structures (ferro- antiferro- ferri-magnets)
- calculate the magnetic phase transition temperature in the mean
field model
- derive an expression for magnetic excitations (spin waves)
- explain the particular magnetic properties of nanoparticles
- describe the principles in a series of magnetic measurement
techniques including magnetization, susceptibility, NMR, Mossbauer
spectroscopy, and neutron scattering
