Course description and aims
Magnetism is an extensive academic discipline including fundamentals and application and has long history. This course teaches fundamentals of magnetism in magnetic insulators.
Remarkable quantum and many-body effects are observed in magnetic phenomena of solid. Starting from the electronic states of magnetic atoms in solid, students learn magnetic interaction between spins such as exchange interaction, magnetic structure of the ground state, phase transition and critical behavior, magnetic excitations, experimental methods and research frontiers in quantum spin systems and strongly frustrated magnets.
Student learning outcomes
Students will acquire the following knowledge and skills from taking this course.
1) Understand the electron state of magnetic atoms (ions).
2) Understand magnetic phase transitions and exchange interaction that drives them.
3) Understand magnetic excitation.
4) Understand experimental methods of magnetism research.
5) Know cutting edge research.
Keywords
Magnetism, spin, crystalline field, exchange interaction, magnetic structure, phase transition, critical behavior, magnetic excitation, quantum spin system, frustration
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
Two-thirds of class is devoted to fundamentals and the rest to advanced content and research frontiers.
The backup lecture for IGP students can be given in English after the class.
