| Research Abstract |
Ternary Ce compounds CeT2Al10(T=Ru and Os) are new Kondo semiconductors which undergo an antiferromagnetic transition. The mechanism of the antiferromagnetic transition in CeT2Al10is expected to be different with typical Ce antiferromagnets because of extraordinary high transition temperature 27K for T=Ru and 28.5K for T=Os. In order to clarify the novel antiferromagnetic transition, we performed the study of neutron scattering, photoemission and substitution effect on T and Al. From this study, the magnetic transition in CeT2Al10should originate from unique electronic structure and the anisotropy of c-f hybridization.
