This suggests that the removal of the polytitanate phase in BCZT-A enables homogeneous and uniform domain switching with little hindrance for domain wall movement. Although a similar effect has been expected for the BCZT-A-Q, where no secondary phases are present, this sample exhibits the lowest 𝑅 𝑆𝑞 and highest IFWHM. This can be explained by the effect of quenching; despite being successful in the second phase removal, this process freezes in the high-temperature concentration of point defects that hinder domain wall movement.
