| Outline of Final Research Achievements |
CeRu2A10 is the first Kondo semiconductor, where the anisotropic c-f hybridization plays an important role. By a small Rh doping into CeRu2Al10, itinerant nature is suppressed and the system is changed to the localized one. In this case, it is not known that the spin gap and charge gap disappear or not. We invesigated thelow temperature specific heat and optical conductivity and found that they disappear rapidly. Then, a decrease of TN is not large. We also found that by Rh doping into the valence fluctuation compound CeFe2Al10, the system is changed to teh localized one.
We also investigated HoR2Al10 (R=Fe, Ru) as a refence system and found the characteristic magnetic phase diagrams, which could be reproduced by the mean field calculation.
