| Title: | Lattice dynamics of orthorhombic perovskite YMnO3 |
| Authors: | Gupta, H C
Ashdhir, P |
| Keywords: | Lattice dynamics
YMnO3
Phonons |
| Issue Date: | 1999 |
| Citation: | Physica B, 262(1-2), 1–4 |
| Abstract: | A short-range force constant model has been applied to investigate the phonons in YMnO
3 perovskite in the orthorhombic phase. The calculations with six stretching and two bending force constants provide a satisfactory agreement for the available Raman and infrared frequencies. Based on the present calculations, the infrared frequencies have been assigned for the first time. |
