Infrared-active phonons in RTiO3 perovskites (R=La,Ce,Pr,Nd,Sm,Gd)
Abstract
The room-temperature reflectance (100–1000 cm-1) of the rare-earth titanites (RTiO3 R=La,Ce,Pr,Nd,Sm,Gd) has been measured. The spectrum for LaTiO3, CeTiO3, and PrTiO3 consists of the three main perovskite vibrational bands. The central band, near 340 cm-1, consists of several barely resolved modes which begin to separate in NdTiO3 and SmTiO3 and which split into two clusters of modes in GdTiO3. These features are correlated with an increasing …
