Abstract

In order to shed light on the electrical and thermal properties of the cage-type CeOs 2Al 10, we investigate this material by measuring electrical resistivity, Seebeck coefficient, thermal conductivity, specific heat, and thermal expansion. The phase transition T 0 ∼ 28 K for CeOs 2Al 10 has been characterized by marked features in all measured physical quantities. Above T o, the electrical resistivity and Seebeck coefficient can be well described by a two-band model with reliable physical parameters. Furthermore, the extracted magnitude of the quasielastic linewidth q f ∼ 30.2 K is found to be consistent with that observed in the neutron scattering experiment. These results are compared to its isostructural compound CeRu 2Al 10.
