摘要: Polarized Raman spectra are reported for scattering from a single oriented antiferromagnetic domain in RbCoF3. Monodomain samples were achieved by the application of small [100] uniaxial stress. Spectra recorded at 2 K using non-absorbed, orange laser light. The D4h symmetry assignments principal features are: 34(Γ+5), 335 (Γ+1 and Γ+1), 420 (Γ+1), 950 (Γ+3) 1050 cm-1 (Γ+1). These results not consistent with prediction previous models magnetic exciton scattering.
