摘要：
A stimulated magnetostriction of an easy-plane singlet onesublattice magnet in a magnetic field directed along its axis of hard magnetization has been considered. It has been shown that the magnetostriction in such a magnetic system is governed by a quantum phase transition belonging to displacement magnetic phase transitions induced by an external field. The amplitude of the stimulated magnetostriction has been demonstrated proportional to the field strength.
