    • Abstract

       

      An empirical interatomic potential for YBa2Cu3O7−δ is determined for different oxygen contents (δ=0 to 1), consisting of Coulomb and short-range interactions. The calculated structure and phonon spectrum, and the results of molecular-dynamics computer simulation on the orthorhombic-to-tetragonal phase transition are in fair agreement with reported experiments.
