| 中文摘要 | We measured the infrared reflectivity of BaFe1.904Ni0.096As2 single crystal from room temperature down to 20 K. Two Drude terms and a Lorentz term well describe the real part of the optical conductivity sigma(1)(omega). We fit the reciprocal of static optical conductivity 1/sigma(1)(0) by the power law rho(T) = rho(0)+AT(n) with n=1.6. The "broad" Drude component exhibits an incoherent background with a T-independent scattering rate 1/tau(b), while the other "narrow" one reveals a T-quadratic scattering rate 1/tau(n), indicating a hidden Fermi-liquid behavior in BaFe1.904Ni0.096As2 compound. |
