Fig. 2

The resistivity of the PdCoO2 a and PtCoO2 b devices, shown in panels c and d, respectively. Each device was sculpted from a single crystal using focused ion beam milling. Electrical contact is made to the crystal via a layer of sputtered gold applied to the top surface. To ensure current homogeneity through the thickness of the measurement channel the current passes along a meander track before entering that channel. The longitudinal and Hall contact pairs for which ρxx(H) and ρxy(H) data are shown in this paper are marked, but the multi-contact geometry allowed for checks that these data were consistent across each sample
