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.
