Outline of Final Research Achievements

Strong hybridization of the 4f states with conduction bands in Ce-based Kondo semiconductors quenches the local magnetic moments and opens a gap in the hybridized band. However, newly found Kondo semiconductors CeT2Al10 (T=Ru, Os) order antiferromagnetically at unexpectedly high temperatures at 28 K. To elucidate this mechanism, we have made Os based samples by doping 4f holes, 5d holes, and 5d electrons, and studied the change in the electronic state by the bulk measurements as well as electron tunneling, optical conductivity, photoemission spectroscopy, and neutron scattering. The effects were found to strongly depend on the three different dopants. However, it is common that the magnetic order occurs after the density of states at the Fermi level decreases significantly on cooling. Thus, we propose that the Lifshitz transition involving the loss of a part of the Fermi surface induces the unusual magnetic order.
