Course content
1. Magnetic properties of nanostructures - introduction to magnetism of solids (magnetic moment, classical and quantum mechanics of spin), magnetic susceptibility, diamagnetism, paramagnetism, crystal field, magnetic interactions among magnetic moments (magnetic dipolar interactions, origin of exchange interactions, direct, indirect, double and anisotropic exchange interactions), ordering of magnetic moments (ferromagnetism, antiferromagnetism, ferrimagnetism, helimagnetism and spin glasses), magnetic domains and Bloch walls (domain formation, magnetization processes, observation of magnetic domains), single-domain magnetic structures (qualitative and quantitative description, Stoner-Wohlfarth model), superparamagnetism, surface and finite size effects, non-interacting and interacting systems of particles (qualitative and quantitative description, Chantrell model, Dormann-Bessais-Fiorani model, Morup model, etc.), spin canting, quantum phase transitions, thin films and multilayer systems, magnetoresistance (anisotropic, exchange and colossal magnetoresistance, quantum Hall effect). 2. "Candidates" of nanostructures - Iron oxides and perovskites. 3. Frustration and spin glasses - topographic and magnetic frustration, qualitative description, conditions for frustrations, spin glasses (randomness of magnetic interactions, amorphous magnets, detection of spin glasses). 4. Magnetooptical phenomena in nanostructures - Faraday effect, Kerr effect. 5. Spintronics - basics of spintronics, suitable materials for spintronic devices, their manufacturing and characterization, injection of spins, transfer of spins, spin polarization, magnetoelectrical devices.

Learning outcomes
The aim of the subject is to familiarize students with basic concepts of magnetism and magnetic phenomena in the nanoworld. The subject is also focused on the experimental observation of magnetic behaviors in the nanoworld. Promising applications of magnetic nanostructures are also mentioned. The candidates of magnetic nanostructures are discussed in details.
Students become familiar with magnetism in nanoworld, basic nanomagnetic phenomena, methods for experimental studying of magnetic properties of nanostructures, and applications of magnetic nanostructures in various fields.
