A Piezoresponse Force Microscopy Study of Ca(x)Ba(1−x)Nb(2)O(6) Single Crystals

Polar structures of Ca(x)Ba(1−x)Nb(2)O(6) (CBN100x) single crystals were investigated using piezoresponse force microscopy. Increasing Ca content results in decreasing domain size and enhancement of the polar disorder. For the composition with x = 0.32 the characteristic domain size is similar to th...

description Polar structures of Ca(x)Ba(1−x)Nb(2)O(6) (CBN100x) single crystals were investigated using piezoresponse force microscopy. Increasing Ca content results in decreasing domain size and enhancement of the polar disorder. For the composition with x = 0.32 the characteristic domain size is similar to that reported for relaxor Sr(0.61)Ba(0.39)Nb(2)O(6) (SBN61). However, decay of an artificial macroscopic domain in CBN32 takes place below the macroscopic transition temperature, contrary to SBN61, where random fields stabilize it above the transition temperature. We can conclude that CBN with 0.26 ≤ x ≤ 0.32 does not display classical relaxor behavior and might be considered as a disordered ferroelectric.
