• 論文の詳細を見る

• Optical properties of R-excitons in LuCrO_3 as well as their change during the magnetic-field-induced spin reorientation have been investigated. It is shown that the polarization characters of the exciton lines agree with the theory of the Frenkel excitons in antiferromagnetic rare-earth orthochromites. By using the available theory, parameters related to the excitation transfer matrix elements of Cr^<3+> ions in LuCrO_3 are determined. The energy shift and intensity change of the exciton lines during the spin reorientation are discussed and compared with those in YCrO_3.
