Magnetic and Electric Field Induced Periodic Deformations in Nematics
This work reports theoretical studies on the occurrence oi a static periodic distortion (PD in a nematic sample under the action of crossed electric (E) and magnetic (H) fields applied on a uniformly aligned initial director configuration (no) Linear stability analysis with rigid anchoring hypothesis is employed For homeotropic alignment of a nematic such as &f1 which has negative dielectric an...
متن کاملSimultaneous near field imaging of electric and magnetic field in photonic crystal nanocavities
The insertion of a metal-coated tip on the surface of a photonic crystal microcavity is used for simultaneous near field imaging of electric and magnetic fields in photonic crystal nanocavities, via the radiative emission of embedded semiconductor quantum dots (QD). The photoluminescence intensity map directly gives the electric field distribution, to which the electric dipole of the QD is coup...
متن کاملElectric-field-induced thermally assisted switching of monodomain magnetic bits
We present a study of the electric-field-induced switching of magnetic memory bits exhibiting interfacial voltage-controlled magnetic anisotropy (VCMA). Switching is analyzed in the single-domain approximation and in the thermally activated regime. The effects of external magnetic fields, magnitudes of the perpendicular anisotropy and VCMA effect, and voltage pulse width on the switching voltag...
متن کاملElectric field induced magnetic anisotropy in a ferromagnet.
We report the first observation of a transient all electric field induced magnetic anisotropy in a thin film metallic ferromagnet. We generate the anisotropy with a strong (approximately 10(9) V/m) and short (70 fs) E-->-field pulse. This field is large enough to distort the valence charge distribution in the metal, yet its duration is too brief to change the atomic positions. This pure electro...
متن کاملElectric tuning of magnetization dynamics and electric field-induced negative magnetic permeability in nanoscale composite multiferroics
Steering magnetism by electric fields upon interfacing ferromagnetic (FM) and ferroelectric (FE) materials to achieve an emergent multiferroic response bears a great potential for nano-scale devices with novel functionalities. FM/FE heterostructures allow, for instance, the electrical manipulation of magnetic anisotropy via interfacial magnetoelectric (ME) couplings. A charge-mediated ME effect...
