Quantum oscillations and high carrier mobility in the delafossite PdCoO${}_2$

Clifford W. Hicks, Alexandra S. Gibbs, Andrew P. Mackenzie +3

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 μΩ-cm, making PdCoO2 the most co…
