Asymmetric counter propagation of domain walls
(2016)
Far from equilibrium systems show different states and domain walls between them. These walls, depending on the type of connected equilibria, exhibit a rich spatiotemporal dynamics. Here, we investigate the asymmetrical ...
Analytic solution of the domain-wall nonequilibrium stationary state
(American Physical Society, 2018-02-28)
Depinning field of a periodic domain wall array in vicinal nanowires
(Journal of Applied Physics, 2009)
Symmetry-dependent domain wall propagation in triangular nanowires
(Elsevier B.V., 2024)
Multiscaling analysis of ferroelectric domain wall roughness
(American Physical Society, 2012-10)
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 ...
Excitations of interface pinned domain walls in constrained geometries
(AIP Publishing LLC, 2017-12-05)
We report a theoretical investigation of the equilibrium pattern and the spectra of head-to-head and Neel domain walls of flat Fe and Py stripes, exchange coupled with a vicinal antiferromagnetic substrate. We show that ...
Experimental evidence of charged domain walls in lead-free ferroelectric ceramics: Light-driven nanodomain switching
(Royal Society of Chemistry, 2018-01)
The control of ferroelectric domain walls at the nanometric level leads to novel interfacial properties and functionalities. In particular, the comprehension of charged domain walls, CDWs, lies at the frontier of future ...
Transient magnetic-domain-wall ac dynamics by means of magneto-optical Kerr effect microscopy
(American Physical Society, 2019-06-01)
The domain wall response under constant external magnetic fields reveals a complex behavior where sample disorder plays a key role. Furthermore, the response to alternating magnetic fields has only been explored in limited ...
Dinâmica de paredes de domínios sob o efeito de correntes elétricas
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2013-11-28)
In this work, we have measured the domain wall velocity in the low field regime and studied
the domain wall dynamics in Joule-annealed amorphous glass-covered microwires with positive
magnetostriction. Such microwires ...
