摘要

An investigation was made of broad phase transitions to the paraelectric state of (l- x)Pb(Yb1/2,Nb1/2)O_3-xPb(Lu1/2Ta1/2)O_3 solid solution for 0.45 ≤X H 0.50. The broadening of these transitions was tbund to depend on the position of the sample in the phase diagram, with the strongest broadening for a composition within the hysteresis range separating the ttrroelectric and anti- ferroelectric states. An interaction mechanism between the ferroelectric and antiferroelectric domains is proposed to explain the broadening of the phase transltlons.
