 Title: Quantum oscillations and high carrier mobility in the delafossite PdCoO2 Authors: Hicks, Clifford WilliamGibbs, Alexandra SarahMackenzie, AndrewTakatsu, HiroshiMaeno, YoshiteruYelland, Edward Alexander Keywords: QC Physics Issue Date: Sep-2012 Citation: Hicks , C W , Gibbs , A S , Mackenzie , A , Takatsu , H , Maeno , Y & Yelland , E A 2012 , ' Quantum oscillations and high carrier mobility in the delafossite PdCoO 2 ' Physical Review Letters , vol 109 , no. 11 , 116401 . Abstract: We present de Haas-van Alphen and resistivity data on single crystals of the delafossite PdCoO2. At 295 K we measure an in-plane resistivity of 2.6 \mu{\Omega}-cm, making PdCoO2 the most conductive oxide known. The low-temperature in-plane resistivity has an activated rather than the usual T^5 temperature dependence, suggesting a gapping of effective scattering that is consistent with phonon drag. Below 10 K, the transport mean free path is 20 \mum, approximately 10^5 lattice spacings and an astoundingly high value for flux-grown crystals. We discuss the origin of these properties in light of our data.
