Abstract

Thermopower of Pr₃Co, Nd₃Co and Sm₃Co are measured in the temperature range from 4.2 K to 280 K. The thermopowers in the high temperature region show negative values for La₃Co and Nd₃Co and a positive value for Sm₃Co. However, that of Pr₃Co shows a small negative constant value. These behaviors are considered in relation to the density of state of Co in R₃Co at the Fermi energy on the basis of Mott's equation of the thermopower.
