Abstract

Recently, Rh-Mg substitution to the delafossite oxide, CuRhO₂ was found to show metallic behavior without lowering mobility. Motivated by this discovery, we study the Mg substitution effects of another oxide. Unfortunately, Rh-Mg substitution in spinel oxide ZnRh₂O₄ was not so successful good as that in CuRhO₂. The room-temperature resistivity and thermopower of ZnRh_1.4Mg_0.6O₄ are 55 mΩcm and 75 μV/K, respectively. This difference may be due to the dimensionality of crystal structure.
