MnF 2A high density perturbation method is employed to calculate the temperature dependence of the two-magnon Raman scattering spectra for the antiferromagnets MnF 2 and FeF 2 below their N茅el temperature. The theory includes the leading order effects of magnon-magnon interactions. A comparison ...
Raman spectra of TiO2, MgF2, ZnF2, FeF2, and MnF2. Phys Rev First-order Raman spectra have been measured at room temperature in five materials of the D4h point group: TiO2, MgF2, ZnF2, FeF2 and MnF2. The experiments... SPS Porto,PA Fleury,TC Damen 被引量: 358发表: 1967年 ...
