授業目標

This class on this semester will be done by "face-to-face".

Rare earth (RE) or transition metal (TM) compounds have attracted a great deal of attention as next generation of the electronic materials “so called Strongly correlated electronic materials”, since these class of materials show unusual electric, magnetic, thermal and optical properties. Such phenomena are derived from a hybridization of the f electrons in RE (d electrons in TM) with the conduction electrons. This lecture will focus on the electronic structures of RE and TM compounds which are very important to understand their unusual properties. To aim at the improvement of the theoretical and experimental (mainly photoemission spectroscopy) knowledge that is needed to understand the electronic structure, the newest information on the electronic structure of strongly correlated materials will be introduced.
The goals of this lecture are to
1. Understand the principles of photoemission spectroscopy.
2. Obtain the basic knowledge about the physical properties of various strongly correlated electron systems.
3. Be able to explain relation between the physical properties and the electronic structures for strongly correlated electron systems.

Printed reference materials will be distributed.
