摘要：
We present results of low-temperature two-magnon resonance Raman excitation profile measurements for single-layer Sr2CuO2Cl2 and bilayer YBa2Cu3O6+delta antiferromagnets over the excitation region from 1.65 to 3.05 eV. These data reveal composite structure of the two-magnon line shape and strong nonmonotic dependence of the scattering intensity on excitation energy. We analyze these data using the triple resonance theory of Chubukov and Frenkel [Phys. Rev. Lett. 74, 3057 (1995)] and deduce information about magnetic interaction and band parameters in these materials.
