Target skills and knowledge: The aim of the course is understanding cooperation properties in magnetic materials from the magnetic features of atoms, radicals and magnetic clusters (Magnetochemistry) and the effects of these magnetic properties on the photoinduced chemical reactions (Spin-Chemistry). Corresponding experimental methods will be introduced, as well as the potential applications in the field of data storage and photovoltaics processes.
Examination methods: Oral examination of about 40 minutes involves two open general questions with the aim of assessing the knowledge of two main topics treated in the course. A number of different specific questions will allow to evaluate the reasoning ability of the candidate about more detailed issues.
Course unit contents: Introduction to phenomenology and principles of magnetism. Paramagnetism and diamagnetism. Long-range order and cooperation: ferromagnetism, antiferromagnetism, ferrimagnetism.
The elementary concepts of paramagnetism and diamagnetism. Brillouin’s equation and Curie-Weiss law. Some Curie law magnets. The Van Vleck’s theory for paramagnetism and diamagnetism. Magnetic properties of metals: paramagnetism of Pauli and diamagnetism of Landau.
Measurement of magnetic susceptibility: the Gouy methods. NMR tecniques. Dipole moments methods: SQUID magnetometry.
Electronic structure of atoms and implications for magnetism. Angular momenta and magnetic moments. Coupling of angular momenta. The electron spin-orbit interactions: perturbation theory and the mixing of states. Spin Hamiltonian and wavefunctions in the Hilbert space. Spin-Spin dipolar interactions and Zero Field Splitting theory. Spin exchange interactions. Superexchange. Ising and Heisenberg models. Ferromagnets and ferrimagnets.
Magnetic properties of free ions. Transition metal ions. The orbital splitting in cubic ligand fields and lower than cubic symmetry systems. Origin of ferromagnetism in inorganic materials. Magnetic properties of molecular crystals. Nanomagnets: magnetism in single molecule systems (SMM) and clusters of ions. Some applications of nanomagnets.
Radicals and biradicals. Photoexcited transient paramagnetic species in photoactive organic materials. Spin polarization processes. Spin-correlated radical ions pairs theory. Polarons and bipolarons in polymeric systems. Spin selective mechanisms in photovoltaics processes. Some applications in spintronics.
Planned learning activities and teaching methods: Classroom lectures.
Additional notes about suggested reading: In-class slides and post-class material will be provided on the whole program of the course.
