Course objectives:
|
The aim of the lecture is to transfer to the students the current knowledge concening magnetism in solids and magentic properties of materials and their measurements, and familiarize the students with magnetic phenomena occurring in the nanoworld and application potential of magnetic (nano)materials.
|
Requirements on student
|
Class attendance. Knowledge of the course topics, ability to discuss about the course topics in wider contexts.
|
Content
|
1. 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)
2. Ordering of magnetic moments (ferromagnetism, antiferromagnetism, ferrimagnetism, helimagnetism and spin glasses), magnetic domains and Bloch walls (domain formation, magnetization processes, observation of magnetic domains).
3. Nanomagnetism: single-domain magnetic structures (qualitative and quantitative description, Stoner-Wohlfarth model), superparamagnetism, surface and finite size effects, spin canting, quantum phase transitions, thin films and multilayer systems.
4. Magnetoresistance (anisotropic, exchange and colossal magnetoresistance, quantum Hall effect).
5. "Candidates" of nanostructures - Iron oxides and perovskites.
6. 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).
7. Applications of magnetic (nano)materials in various technological, medical, and environmental fields.
