摘要：
An interatomic potential for YBa2Cu3O7- based on Coulomb and short-range interactions is proposed. The calculated minimum energy structure, phonon spectrum, and the results of the molecular-dynamics computer simulation up to 1300 K on thermal expansion and the orthorhombic-to-tetragonal phase transition are in fair agreement with reported experiments. © 1990 The American Physical Society.
