Inherent spin-polarization coupling in a magnetoelectric vortex

Solid-state materials are currently being explored as a platform for the manipulation of spins for spintronics and quantum information science. Using dilute Fe3+-doped ferroelectric PbTiO3− SrTiO3 superlattices as a model system, we demonstr...

Metastable vortex-like polarization textures in ferroelectric nanoparticles of different shapes and sizes

The dependence of the polarization texture topology in ferroelectric (FE) PTO nanoparticles, embedded in a dielectric matrix, on the particle shape and size was investigated with a time-dependent Landau-Ginzburg-Devonshire approach combined ...

Vortex-strength models in hydrodynamics

By examining the unsteady Taylor vortex the paper shows how three different vortex-strength models work. This comparison includes the conventional circulation for an ideally axisymmetric vortex. It is emphasized that the
