We have computed the frequencies of selected normal modes in perovskite PbZrO 3 (PZ) as a function of lattice parameter using local density-functional theory variational linear response. The harmonic instabilities of the perovskite structure which freeze in to give the orthorhombic antiferroelectric
A high-pressure single-crystal x-ray diffraction study of perovskite-type MgSiO 3 has been completed to 12.6 GPa. The compressibility of MgSiO 3 perovskite is anisotropic with b approximately 23% less compressible than a or c which have similar compressibilities. The observed unit cell compression g
