摘要：
We have studied the optical absorption spectra of the two-dimensional antiferromagnet Rb2MnxCd1-xCl4, where x changes over the range 1-0.4. An influence of the temperature, the external magnetic field, and the uniaxial pressure on the fine structure of optical absorption related to the T-4(2g)(D-4) excited state of the Mn2+ ions have been investigated. Exciton-magnon, exciton-phonon and other multiparticle excitations were found in the optical spectrum. Magnetic phase diagram in the x - H coordinates was obtained. (C) 2002 Elsevier Science B.V.
