The Raman spectra of epitaxial thin films of La2NiMnO6 on (001)-oriented LaAlO3 substrates have been measured in several exact scattering configurations between 12 and 773 K. The evolution of the spectra with increasing temperature is consistent with a transition from the monoclinic P12(1)/n1 to rhombohedral R3 structure. The spin-phonon coupling results in significant softening of the phonon mode involving stretching vibrations of the (Ni/Mn)O-6 octahedra. The anomalous softening extends above T-C=275 K, indicating the presence of short range ordering up to 400 K. (c) 2007 American Institute of Physics.
