Anomalous magnetotransport in the heavy-fermion superconductor Ce2PdIn8

Abstract

The normal state behavior in the heavy-fermion superconductor Ce2PdIn8 has been probed by means of Hall coefficient (RH) and transverse magnetoresistivity (MR) measurements. The results indicate the predominance of contributions from antiferromagnetic spin fluctuations at low temperatures. Anomalous non-Fermi-liquid-like features, observed below 8 K in both RH(T) and MR(T), are related to underlying quantum critical point, evidenced before in the specific heat and the electrical resistivity data. The magnetotransport in Ce2PdIn8 is shown to exhibit specific types of scaling that may appear universal for similar systems at the verge of magnetic instability.
