Attributions of rich Raman modes and their temperature dependences in Mn4Nb2O9 single crystals
It is an important task of single crystal Raman spectroscopy to identify the lattice vibration modes in terms of symmetry and further study the temperature-dependent behavior of various Raman modes. A4B2O9 (A = Co, Mn, Fe; B = Nb, Ta) type magnetodielectric or magnetoelectric materials represented b...
