摘要:
The electromechanical nonlinearity of a bismuth tellurite single crystal (Bi2TeO5) is investigated. It is revealed that the noncentral forces of interatomic interaction dominate in this material. The relation between the structural features of Bi2TeO5 and its elastic properties is analyzed. (C) 2001 MAIK "Nauka/Interperiodica".
