| Research Abstract |
The interesting phenomena of the strongly correlated f electron system arise from the nearly localized nature of the f electron on the border between itinerant and localized. By applying chemical pressure or by alloying, we have varied successfully the nature of the f electron to a large extent in a number of typical strongly correlated f electron compounds. We have also revealed the changes in the physical and electronic properties associated with the change in the f electron nature by using the de Haas . van Alphen effect as a main experimental tool.
