Quasi-two-dimensional Fermi surfaces of the heavy-fermion superconductor Ce${}_2$PdIn${}_8$

Abstract

We report low-temperature de Haas-van Alphen (dHvA) effect measurements in magnetic fields up to 35 T of the heavy-fermion superconductor Ce${}_2$PdIn${}_8$. The comparison of the experimental results with band-structure calculations implies that the 4$f$ electrons are itinerant rather than localized. The cyclotron masses estimated at high field are only moderately enhanced, 8 and 14 $m_0$, but are substantially larger than the corresponding band masses. The observed angular dependence of the dHvA frequencies suggests quasi-two-dimensional Fermi surfaces in agreement with band-structure calculations. However, the deviation from ideal two dimensionality is larger than in CeCoIn${}_5$, with which Ce${}_2$PdIn${}_8$ bears a lot of similarities. This subtle distinction accounts for the different superconducting critical temperatures of the two compounds.
