title: Phase transition of displacive type in PbZr(0.94)Ti(0.06)O(3).
abstract: In this paper the electrostrictive properties above T(εmax), represented by the field-related M and polarization-related Q coefficients, have been reported for Pb(Zr(1-x)Ti(x))O(3) ceramics with x = 0.03-0.10. Among M(11)(T) and Q(11)(T) dependences, those found for Pb(Zr(0.94)Ti(0.06))O(3) have been clearly distinguished. In this case, the Q(11)(T) dependence is linear in the whole temperature range above T(εmax). Experimental and theoretical analysis of the M(11)(T) dependences has shown that the phase transition to the ferroelectric phase in Pb(Zr(0.94)Ti(0.06))O(3) ceramics seems to be of the displacive type.
