After completion of the course the student should: • Understand the relation between the electron structure of crystalline solids and their dielectric, magnetic and superconducting properties. • Understand and use some standard models for calculations of polarisation, magnetisation and superconductivity in solids.
Dielectric properties: Sources of polarisation, electric fields inside dielectrics, depolarisation, microscopic theories of polarisation. Paramagnetism och magnetic ordering: Quantum theory of dia- and paramagnetism, exchange interaction, magnetic order: ferro, ferri- and antiferromagnetism, magnons, anisotropy and domains, soft and hard ferromagnetic materials. Superconductivity: Phenomenological description, BCS theory, thermodynamics, London equation, thin films, type I and type II superconductors, flux quantisation, electron tunnelling, Josephson effect.
Lectures, lessons and laboratory work.
Written examination at the end of the course (4 credits), laboratory course (1 credit).
