Constraints on the Fermi liquid scaling of the optical conductivity in MnSi

ORAL

Abstract

We have developed a new method of terahertz time-domain spectroscopy (THzTDS) analysis to test the frequency-temperature scaling relation of Fermi-liquid theory, ρ(ν,T) = [σ(ν,T)]-1=ρ0+Α[(hν)2+(pπkBT)2], where p=2. We apply this to THzTDS measurements of MnSi thin films over a temperature range T = 5-300 K and a frequency range ν = 0.1-3 THz.
