Abstract

We report measurements and analyses of resistivity, thermopower and the Hall coefficient of single-crystalline samples of the layered Rh oxide K 0.49RhO2. The resistivity is proportional to the square of the temperature up to 300K, and the thermopower is proportional to the temperature up to 140K. The Hall coefficient increases linearly with the temperature above 100K, which is ascribed to the triangular network of Rh in this compound. The different transport properties between NaxCoO 2 and K0.49RhO2 are discussed on the basis of the different bandwidth between Co and Rh evaluated from the magnetotransport.
