Electrodynamics of the antiferromagnetic phase in URu2Si2
Abstract
We present data on the optical conductivity of URu2−x(Fe,Os)xSi2. While the parent material URu2Si2 enters the enigmatic hidden order (HO) phase below 17.5 K, an antiferromagnetic (AFM) phase is induced by the substitution of Fe or Os onto the Ru sites. We find that both the HO and the AFM phases exhibit an identical gap structure that is characterized by a loss of conductivity below the gap energy with spectral weight transferred to a narrow …
