abstract
Raman scattering spectra of the single crystalline PrRu4P12 have been measured in the temperature region between 1.5 K and 300 K. Below TMI, new peaks appear at phonon region and these peaks are assigned as the Raman-active phonons with Pm^3 symmetry. While, the broad spectra in the lower energy region than 200cm.1 become sharp below TMI and the detailed polarization measurements conclude that these are the crystal field excitations(CF) due to two-different Pr sites. Furthermore, temperature dependence of the CF energy levels for Pr2 has been clarified.Raman scattering spectra of the single crystalline PrRu4P12 have been measured in the temperature region between 1.5 K and 300 K.
