Domain wall dynamics and neuronic crackling noise
… likely to be present in each of the different domain walls that develop in four ferroelastic phases. Tetragonal and orthorhombic shear strains have values of 4-6% and 2-3% respectively, and are dominated by coupling with the order parameter for antiferroelectric-type displacements. Conversely, …

Charged domain wall phenomena and associated negative capacitance in boracites
… technologies typically rely on ferroelectric domains, that is, macroscopic regions of uniformly oriented dipole moments within the crystal. Over the past decade, however, attention has now turned to the entity that separates these domains, the domain wall, due to their widely reported enhanced …

Domain patterns and domain wall dynamics in small-scale ferroelectrics
… of highly-ordered packets of 90° ferroelastic domains, or ‘superdomains’, which exhibit a net in-plane polarisation aligned (or anti-aligned) with the switching field. Ferroelectric switching was mediated mainly by the motion of boundaries separating these superdomains whilst the ferroelastic …

THE STUDY OF PERPENDICULARLY MAGNETIZED COFE/PD MULTILAYERS FOR DOMAIN WALL MOTION
We focus the studies of DW motion in a CoFe/Pd multilayer-based nanowire with strong PMA. We find that high PMA, low saturation magnetization, narrow DW width and high spin polarization can induce low threshold current density for DW motion in CoFe/Pd superlattice-like multilayer films. Next, we …

Magnetic domain walls driven by interfacial phenomena
A domain wall in a ferromagnetic material is a boundary between differently magnetized regions, and its motion provides a convenient scheme to control the magnetization state of the material. Domain walls can be confined and moved along nanostrips of magnetic thin films, which are proposed …
