Course objectives
The aim of the course is to provide an introduction to magnetic phenomena in molecular and solid state systems of inorganic and bioinorganic nature. Emphasis is given on the design and study of magnetic molecules and materials with tunable properties and on their chemical reactivity. Topics include classical versus quantum mechanical pictures, paramagnetism, crystal field effects, dipolar and exchange interactions, spin chemistry and spintronics.
