Impact of 3D curvature on the polarization orientation in non-Ising domain walls
Ulises Acevedo-Salas, Boris Croes, Yide Zhang +11
Ferroelectric domain boundaries are quasi-two-dimensional functional interfaces with high prospects for nanoelectronic applications. Despite their reduced dimensionality, they can…
Electric field control of labyrinth domain structures in core-shell ferroelectric nanoparticles
Anna N. Morozovska, Eugene A. Eliseev, Salia Cherifi-Hertel +2
In the framework of the Landau-Ginzburg-Devonshire (LGD) approach, we studied the possibility of controlling the polarity and chirality of equilibrium domain structures by a homoge…
Flexo-Sensitive Polarization Vortices in Thin Ferroelectric Films
Anna N. Morozovska, Eugene A. Eliseev, Sergei V. Kalinin +1
We consider theoretically the influence of the flexoelectric coupling on the spatial distribution and temperature behavior of spontaneous polarization for several types of stable d…
Chiral Polarization Textures Induced by the Flexoelectric Effect in Ferroelectric Nanocylinders
Anna N. Morozovska, Riccardo Hertel, Salia Cherifi-Hertel +3
Polar chiral structures have recently attracted much interest within the scientific community, as they pave the way towards innovative device concepts similar to the developments a…
Flexo-Elastic Control Factors of Domain Morphology in Core-Shell Ferroelectric Nanoparticles: Soft and Rigid Shells
Eugene A. Eliseev, Anna N. Morozovska, Riccardo Hertel +4
Within the framework of the Landau-Ginzburg-Devonshire approach we explore the impact of elastic anisotropy, electrostriction, flexoelectric couplings, and mismatch strain on the d…
Ultrafast dynamics of a magnetic antivortex - Micromagnetic simulations
Sebastian Gliga, Ming Yan, Riccardo Hertel +1
The antivortex is a fundamental magnetization structure which is the topological counterpart of the well-known magnetic vortex. We study here the ultrafast dynamic behavior of an i…
Current-induced magnetic vortex core switching in a Permalloy nanodisk
Y. Liu, S. Gliga, R. Hertel +1
We report on the switching of a magnetic vortex core in a sub-micron Permalloy disk, induced by a short current pulse applied in the film plane. Micromagnetic simulations including…
Nanomagnetic toggle switching of vortex cores on the picosecond time scale
R. Hertel, S. Gliga, M. Fähnle +1
We present an ultrafast route for a controlled, toggle switching of magnetic vortex cores with ultrashort unipolar magnetic field pulses. The switching process is found to be large…
Three-dimensional magnetic flux-closure patterns in mesoscopic Fe islands
R. Hertel, O. Fruchart, S. Cherifi +4
We have investigated three-dimensional magnetization structures in numerous mesoscopic Fe/Mo(110) islands by means of x-ray magnetic circular dichroism combined with photoemission…
Angular-dependence of magnetization switching for a multi-domain dot: experiment and simulation
O. Fruchart, J. C. Toussaint, P. O. Jubert +4
We have measured the in-plane angular variation of nucleation and annihilation fields of a multi-domain magnetic single dot with a microsquid. The dots are Fe/Mo(110) self-assemble…
