Syllabus
  • 1. Magnetic properties of individual atoms and exchange interaction a free atom in a magnetic field terms, the Hund rules magnetic monments of atoms in a solid interaction of magnetic moments example: H2 molecule the Heissenberg hamiltonian the Weiss theorz of molecular field the Curie-Weiss law 2. Magnetism of valence electrons the spin density functional the Stoner model antiferromagnetism and spin waves magnetic properties of alloys surface magnetic properties 3. Magnetic properties of thin layers magnetic anizotropy magnetization of thin layers magnetic phase transition magnetic domains in thin layers magnetic multilayers 4. Exchange interaction between magnetic layers Dependence on the properties of the spacer layers Dependence on the interface properties 5. Magnetoresistance Anisotropic magnetoresistance (AMR) Giant magnetoresistance (GMR) Colossal magnetoresistance (CMR) Eelements of the theoretical description of GMR Spinvalves 6. Growth of thin layers, MBE method In-situ analysis of the layers Growth kinetics Ecamples of the growth of magnetic layers 7. Experimental methods Magnetometry Atoms as measuring devices neutron scattering absorption and ascattering of x-rays
