Figure 1
Polarized Raman spectra of hexagonal LuMnO3 single crystal at 21 K obtained in the 
and 
configurations using 633 nm red laser.
The broad band of 710–880 cm−1 in single crystal is much more asymmetric than that in thin film. This may indicate more possible modes of magnon scattering with similar energies in single crystal. Mn3+ has S = 2, “multi-spin-flipping” magnon mode could be excited in one or more Mn3+ ions.
