Skyrmions, found in Magnetic Systems, now show to also exist in Ferroelectrics

Schematic representation of the structure and dipolar configuration of the vortex state.

Schematic representation of the structure and dipolar configuration of the vortex state. The structure consists of a cylindrical BaTiO3 (BTO) nanowire with a radius R of 2.7 nm (seven lattice constant units) embedded in a SrTiO3 (STO) matrix with lateral sides along the [100] and [010] directions of nx=ny=36 lattice constant units, and a length nz=6 along the [001] pseudocubic direction. (b) Cross-sectional dipolar configuration of the (Vxy|FEz) state characterized by a vortex pattern in the z-planes co-occurring with an electrical polarization along the [001] direction.

Skyrmions are non-coplanar swirling field textures. Ferroelectrics convert changes in mechanical energy into electrical energy and vice versa...
