High-temperature resistivity of URh2Ge2

We present a study of the anomalous resistivity, with a large rho and negative temperature coefficient drho/dT, of the moderately disordered uranium heavy fermion compound URh2Ge2. We establish that the anomalous behavior persist up to high temperatures, i.e., 620K {approximately equal to}2ThetaD, w...

Zusammenfassung:	We present a study of the anomalous resistivity, with a large rho and negative temperature coefficient drho/dT, of the moderately disordered uranium heavy fermion compound URh2Ge2. We establish that the anomalous behavior persist up to high temperatures, i.e., 620K {approximately equal to}2ThetaD, with ThetaD as the Debye temperature. Our finding reinforces the clear comparison of the transport behavior of URh2Ge2 to that of metallic glasses.
