    Abstract

    We have explored the structural, magnetic, and thermoelectric properties of the CePd 3-xPt x (0 <x <1) solid solution. The similar chemical properties of palladium and platinum appear to result in a minimal perturbation to the intermediate valent state that is responsible for high Seebeck coefficient, while the large mass difference between the two elements significantly reduces the lattice thermal conductivity. The result is a 40% increase of the thermoelectric figure of merit at 100 K and a 30% increase at 300 K; the latter value is the highest value ever reported for any CePd 3-based material.
