摘要

The Raman-active phonons in orthorhombic perovskite-like YMnO3 and LnMnO3 are studied by measuring Raman spectra in various scattering configurations and by calculations of the lattice dynamics (LDC). The much larger line widths and strong variation of the Raman spectra of LaMnO3 with increasing laser power provide evidence for a structural instability.
