Quasi two-dimensional Fermi surface topography of the delafossite PdRhO${}_2$

Abstract

We report on a combined study of the de Haas-van Alphen effect and angle resolved photoemission spectroscopy on single crystals of the metallic delafossite PdRhO${}_2$ rounded off by \textit{ab initio} band structure calculations. A high sensitivity torque magnetometry setup with SQUID readout and synchrotron-based photoemission with a light spot size of $50\mu \mathrm{m}$ enabled high resolution data to be obtained from samples as small as $150\times 100\times 20(\mu \mathrm{m}{)}^3$. The Fermi surface shape is nearly cylindrical with a rounded hexagonal cross section enclosing a Luttinger volume of 1.00(1) electrons per formula unit.
