Lattice dynamics and spin-phonon coupling in CaMn sub(2)O sub(4): A Raman study

We present polarized Raman spectra of CaMn sub(2)O sub(4) (marokite) measured in several exact scattering configurations from oriented single crystals. Most of the 11A sub(g) + 12B sub(1g) + 10B sub(2g) + 9B sub(3g) Raman-allowed modes are identified and assigned to definite atomic motions by compar...
