Abstract

The degeneracy of normal vibrations is investigated for an arbitrary wave‐vector of the Brillouin zone, and some conclusions are drawn about their properties in the [0, 1, 0], [1, 1, 0] and [1, 1, 1] directions.

Critical radius (r C ) for cubic perovskite structure is an important factor affecting the migration energy of oxygen ions. The monotonic dependence of the critical radius on the ionic radii of A-and B-site cations in cubic perovskite ABO 3 structure was systematically investigated by strict mathema
