Outline of Final Research Achievements |
CeT2Al10 (T = Ru, Os) shows antiferromagnetic ordering and Kondo semiconducting behavior due to the hybridization between 4f electrons of Ce and conduction electrons. Because these two phenomena are not believed to happen at the same time, the final goal of this study is to clarify a mechanism behind these behavior. The purpose of this study is “Searching new material by high temperatures and high pressures” and “Investigating crystal structure at low temperatures and under high pressures” so that we can investigate CeT2Al10 from different point of views. We revealed that the shrinkage along a and c axis largely affects physical properties and clarified that the temperature dependence of shrinkage in the crystal structure is insensitive to changing T site.
