Quantum criticality in Ce2PdIn8: thermoelectric study    [PDF]

Marcin Matusiak, Daniel Gnida, Dariusz Kaczorowski

We report the Nernst effect (v) and thermoelectric power (S) data for the
Ce2PdIn8 heavy-fermion compound. Both S and v behave anomalously at low
temperatures: the thermopower shows a Kondo-like maximum at T = 37 K, while the
Nernst coefficient becomes greatly enhanced and field dependent below T ~ 30 K.
In the zero-T limit S/T and v/T diverge logarithmically, what is related to
occurrence of the quantum critical point (QCP). Presented results suggest that
the antiferromagnetic spin-density-wave scenario may be applicable to QCP in
Ce2PdIn8.
