- 論文の詳細を見る
Optical absorption spectra corresponding to the 'A..='E. transition of Cr" inRCr0, (R=Er, Ho, Dy and Tb) were investigated. The exciton lines (7?) withDavydov splitting, and an electric dipole band (7?') at lower energy side were observedin all compounds. From the temperature and external magnetic field dependences ofthe 7?' band, itis concluded that the 7?' band in RCrO. (R=Er, Ho, Dy and Tb) is theCr" exciton localized by the magnetostriction which is caused by the R" spin fluctua-tion or by the static disorder (magnetic domains or magnetic stacking faults) of theR" spin configuration.In the case of ErCr0., besides this 7?' band, a few weak bands were observed in theneighborhood of the R lines, which correspond to the combined excitation of a Cr" excitonand a Er" spin flip.
