Abstract

We explore the electronic and magnetic properties of superconducting iron pnictide films by probing their infrared Hall conductivity as a function of probe energy (0.1-1.3 eV), temperature (10-300 K) and magnetic field (B = 0-7 T). We find hysteretic behavior in the complex infrared Faraday angle, theta {F}, at lowB over the entire temperature range. At higher B, theta { mathrm{F}} is linear in B and we observe a peak in the high B-field slope near 50 K, which may be related to the superconducting phase of the films.
