Thermal stability studies of alternating current poled Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals grown by solid-state crystal growth
single crystals are of great importance due to their limited operational temperatures in devices. Herein
to elucidate how poling conditions influence thermal stabilities
we investigated direct current (DC) and alternating current (AC) poled Pb(Mg

(PMN-29PT) crystals grown by solid-state crystal growth
which guarantees more compositional uniformity. Our experiments show that the dielectric permittivity of the DC and AC poled crystals are 3560 and 4970
respectively
after annealing at 99.6°C
implying AC-poling prevails in enhancing thermal stabilities of relaxor-PbTiO

single crystals. The mechanism behind the dissimilar thermal stabilities can be attributed to different domain configurations.
