- 論文の詳細を見る
The absorption spectra ^6A_<1g<⇾^4T_<2g>(^4D) of Mn^<+2> in the layer type antiferromagnet (C_2H_5NH_3)_2MnCl_4 were measured. An absorption band caused by electric dipole was observed, which has an anomalous shape with cut-offs at the low as well as the high energy sides. The temperature dependence of its intensity suggests that it is a magnon sideband. The anomalous shape of this band could be reproduced in calculation as magnon sideband, taking account of the magnon dispersion and the exciton dispersion due to inter- and intra-sublattice transfers. Measurements of the uniaxial stress effect were also undertaken to investigate details of the behaviours of this magnon sideband.
