Quantum criticality in Ce2PdIn8: thermoelectric study
arXiv:1202.4079 · doi:10.1103/PhysRevB.84.115110
Abstract
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.
