N2 - The authors performed an optical spectroscopy to observe the electronic structure of L 10 -type ordered Mn-based alloys. The effect of disorder on pseudogap formation in Mn1-x Ptx (x=0.47, 0.50, 0.51, and 0.54) and Mn1-x Pdx (x=0.502, 0.515, and 0.535) alloys has been clarified. The optical reflectivity shows a clear dip around 0.5 eV for both MnPt and MnPd alloys, which corresponds to the pseudogap formation. On the other hand, the pseudogap is rather unclear in the other nonequiatomic compositions. This indicates that the pseudogap formation is deeply related to the degree of the ordering in the Mn-based alloys.
