| Outline of Final Research Achievements |
In this study, we have investigated compounds that have the possibility of fluctuation of the valence , orbital , spin and so on, and revealed their properties. Main results are listed below. (1) The detail phase diagram under pressure of pressure induced conductor CePtSi2 was constructed. (2) We prepared poly- and single crystals of CePtGe2, and we revealed it shows ntiferromagnetic transition at 3.8 K. (3) We discovered new compound SmPtSi2 and revealed that it show two step transitions at TH = 8.6 and TL = 5.6 K.
