| Inhalt | The lecture introduces students to the field of strongly correlated materials and their magnetic properties. Various magnetic model systems with strong correlations are covered, and their ground states and excitations are discussed. An introduction to the theoretical foundations of these model systems will be discussed, and in parallel, important experimental methods used to explore these properties will be discussed. Lecture topics: - Origin of magnetic degrees of freedom and interactions - Magnetism in non-correlated materials: ordered magn. structures and spin waves - Magnetism in metals - Low-dimensional magnetism: 1D and 2D magnetism - Frustrated magnetism and complex magnetic structures/excitations - Multiferroic materials, spin-lattice couplings - Spin liquids, and their excitations - Skyrmions - Magnetic superconductors - 1-2 experimental methods are discussed per double lesson: - Diffraction, - Resonant Elastic X-ray scattering (REXS), - Angle-Resolved Photo Emission Spectroscopy (ARPES), - Resonant Inelastic Xray scattering (RIXS), - Neutron spectroscopy, - THz spectroscopy, - Raman scattering |
