Magnetic molecular materials with paramagnetic lanthanide ions

The diverse magnetic properties of lanthanide-based magnetic molecular materials are introduced in the following organization. First, the general aspects of magnetic molecular materials and electronic states of lanthanide ions are introduced. Then the structures and magnetic properties are described and analyzed for molecules with one lanthanide ion, 4f-4f, 4f-3d and 4f-p magnetic coupling interactions. In each section, magnetic coupling, magnetic ordering and magnetic relaxation phenomenon are briefly reviewed using some examples. Finally, some possibilities of developing magnetic molecular materials containing lanthanide ions are discussed in the outlook part.
