Non-Fermi liquid behavior and scaling of low frequency suppression in optical conductivity spectra of CaRuO${}_3$

Y. S. Lee, Jaejun Yu, J. S. Lee +4

Optical conductivity spectra ${\sigma }_1(\omega )$ of paramagnetic CaRuO${}_3$ are investigated at various temperatures. At T=10 K, it shows a non-Fermi liquid behavior of $σ_1(ω)\sim 1/ω^{\frac…
