Effect of sample thickness on the mobility of domain walls in thin ferroelectric films of lead zirconate-titonate and lead titanate
Repolarization in ferroelectric films of lead zirconate-titanate Pb(Zi0.5Ti0.5)O3 and lead titanate PbTiO3 during continuous cyclic switching under the influence of an external field of rectangular form is investigated. The mobility of domain walls μ is calculated for different thicknesses of the studied films according to the experimental values of switching time τs.
