Anomalous transport properties in the filled skutterudites

Abstract

We report the experimental results on resistivity, Hall coefficient and thermoelectric power in REFe4P12 single crystals (RE: La, Ce, Pr and Nd), with a special emphasis on the magnetic field effect on PrFe4P12 that is one of the most attractive skutterudites. In all the transport properties of PrFe4P12, clear anomalies, anisotropic with respect to the magnetic field direction, have been observed associated with the metamagnetic transition. Unusual features found in the magneto-transport properties point to the unique ground state of this compound. © 2002 Elsevier Science B.V. All rights reserved.
