内容記述 | Electronic structures of the filled-skutterudite compounds PrRu4P12 and SmRu4P12, which undergo a metal-insulator transition (MIT) at TMI=60 K and 16 K, respectively, have been studied by means of optical spectroscopy. Their optical conductivity spectra have clearly revealed an energy gap of ~10 meV below TMI. The detailed temperature and energy dependences of the energy gap are shown, which give much more information about the gap compared with that from the electrical resistivity experiment. For PrRu4P12, in addition, optical phonon peaks in the spectra show anomalies upon the MIT, including broadening and shifts at TMI and an appearance of new peaks below TMI. These results are discussed in terms of density waves or orbital ordering previously predicted for these compounds | |||||||||||
