Using multiscaling analysis, we compare the characteristic roughening of ferroelectric domain walls in Pb(Zr0.2Ti0.8)O3 thin films with numerical simulations of weakly pinned one-dimensional interfaces. Although at length scales up to L(MA)≥5  μm the ferroelectric domain walls behave similarly to the numerical interfaces, showing a simple monoaffine scaling (with a well-defined roughness exponent ζ), we demonstrate more complex scaling at higher length scales, making the walls globally… 
Domain wall roughness in stripe phase BiFeO3 thin films.
TLDR
Using the model system of ferroelectric domain walls, the effects of long-range dipolar interactions and periodic ordering on the behavior of pinned elastic interfaces are explored and it is suggested that a random field-dominated pinning, combined with stronger disorder and strain effects due to the step-bunching morphology of the samples, could be the dominant source of pinning in the system.

Domain growth dynamics in PMN-PT ferroelectric thin films
Pb(Mg1/3Nb2/3)O3–PbTiO3 (PMN-PT) ferroelectric thin films have been widely used in many areas due to the outstanding piezoelectric and electromechanical properties. Although many studies have been
Universality classes of the domain-wall creep motion driven by spin-transfer torques.
TLDR
This investigation reveals that the disorder-induced pinning effect on the domain-wall rotation alters the universality class of the creep motion, and the scaling relation between μ and ζ based on certain simplified assumptions is valid for the nonadiabatic spin-transfer torque, while invalid for the adiabatic one.

Domain wall roughness in epitaxial ferroelectric PbZr0.2Ti0.8O3 thin films.
TLDR
The static configuration of ferroelectric domain walls was investigated using atomic force microscopy on epitaxial PbZr( 0.2)Ti(0.8)O(3) thin films to give an effective domain wall dimensionality of d = 2.5, in good agreement with theoretical calculations for a two-dimensional elastic interface in the presence of random-bond disorder and long-range dipolar interactions.

Fractal dimension and size scaling of domains in thin films of multiferroic BiFeO3.
TLDR
A general model is proposed for ferroelectrics, ferroelastics or ferromagnetic domains which relates the fractal dimension of the walls to domain size scaling.
Fracture surfaces as multiscaling graphs.
TLDR
It is shown that 2D fracture does not belong to any of the known kinetic roughening models, and the presence of multiscaling offers a stringent test for any theoretical model; it is demonstrated that a recently introduced model of quasistatic fracture passes this test.

TLDR
The statistical distribution function for the height fluctuations of brittle fracture surfaces is analyzed using extensive experimental data sampled on widely different materials and geometries and discusses for the latter, the relevance of a multiaffine analysis and the influences of the discreteness resulting from material microstructures or experimental sampling.
