Low-energy electronic properties of clean CaRuO${}_3$: elusive Landau quasiparticles

M. Schneider, D. Geiger, S. Esser +8

We have prepared high-quality epitaxial thin films of CaRuO${}_3$ with residual resistivity ratios up to 55. Shubnikov-de Haas oscillations in the magnetoresistance and a $T^2$ tempe…
