  • Zone center phonons of orthorhombic perovskite YAlO3 

    Gupta, H C; Ashdhir, P (1999)
    A short range force constant model has been applied to investigate the phonons in YAlO3 perovskite in the orthorhombic phase. The calculations with six stretching and one bending force constants provide a satisfactory ...
