It was shown that 1%Eu-PZT films have the highest Rayleigh constant, which indicates the minimal interaction of defect-domain walls and high contributions to dielectric and polarization. The high mobility of domain walls, combined with the obvious improved crystallization of 1%Eu-PZT results in the increase of dielectric constant and remanent polarization.
