Piezoresponse force microscopy (PFM) probes the mechanical deformation of a sample in
response to an electric field applied with the tip of an atomic force microscope. Originally …

Ferroelectric materials provide a useful model system to explore the jerky, highly nonlinear
dynamics of elastic interfaces in disordered media. The distribution of nanoscale switching …

Amorphous solids yield at a critical value Σ c of the imposed stress Σ through a dynamical
phase transition. While sharp in athermal systems, the presence of thermal fluctuations …

Abstract Domain walls separating differently oriented polarization regions of ferroelectric
materials are known to greatly impact nanoscale materials and device functionalities …

Self-affine rough interfaces are ubiquitous in experimental systems, and display
characteristic scaling properties as a signature of the nature of disorder in their supporting …

We study both experimentally and theoretically the driven motion of domain walls in
extended amorphous magnetic films patterned with a periodic array of asymmetric holes. We …

We report piezo-response force microscopy studies of the static and dynamic properties of
domain walls (DWs) in 11 to 36 nm thick films of crystalline ferroelectric poly (vinylidene …

Understanding and controlling the motion, stability, and equilibrium configuration of
ferroelectric domain walls is key for their integration into potential nanoelectronic …

We report the competing effects of disorder pinning and thermal roughening on ferroelectric
domain walls as a function of temperature in epitaxial Pb Zr 0.2 Ti 0.8 O 3 thin films …

The nonlinear response of a ferroic to an applied field has been studied through the
phenomenological Rayleigh Law for over a hundred years. Yet, despite this, the …
