Description
We have measured optical conductivity spectra σ(ω) of CeNi1-xCoxGe2 at several temperatures. The σ(ω) spectra exhibit two peaks in middle infrared regions at low temperatures. The peaks show a strong temperature dependence and disappear above a characteristic temperature (T*) at last. We suggest that the middle infrared peaks arise from transitions between d-states below EF and c-f hybridization states just above EF
