The spin Hall effect is a phenomenon in which an electric field induces a spin Hall current. In this Letter, we examine the inverse effect that, in a ferromagnetic conductor, a charge Hall current is induced by a spin motive force, or a spin-dependent effective "electric" field E_{s}, arising from the time variation of magnetization texture. By considering skew-scattering and side-jump processe...

The behaviour of planar samples of an antiferroelectric liquid crystal under DC electric field has been studied through observations with a polarizing microscope In the ferroelectric phase the dechiralization lines have not been observed under a vanishing electric field. They appeared with the increasing field. To explain that effect, we show by analysing the

We describe the terahertz emission from multiple filaments in air in the presence of an external electric field. A strong enhancement of the radiated terahertz energy is obtained by the combined effect of terahertz field interference and presence of a static electric field.

First-principles calculations are performed to investigate the structures, electrical, and magnetic properties of compressive BiFeO3 films under electric-field and pressure perpendicular to the films. A reversible electric-field-induced strain up 10% is achieved in the compressive BiFeO3 films. The giant strain originates from rhombohedral-tetragonal (R-T) phase transition under electric-filed,...

In this paper, a new scheme is proposed to remove the spiral wave in a two-dimensional Fithhugh–Nagumo type equation by introducing a class of vortex electric field into the media. A long electric solenoid with large pipe diameter is used to generate a spatial magnetic field and the intensity of magnetic field B is controllable. A vortex electric field could be induced by changing the external ...
