Electric-field-induced Skyrmion distortion and giant lattice rotation in the magnetoelectric insulator Cu2OSeO3.
Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortexlike objects, display a magnetoelectric coupling and can be manipulated by externally applied electric (E) fields. Here, we explore the E-field coupling to the magnetoelectric Skyrmion lattice phase, and study the response using neutron scattering. Giant E-field induced rotations of the Skyrmion lattice a...
متن کاملElectric field control of the skyrmion lattice in Cu2OSeO3.
Small-angle neutron scattering has been employed to study the influence of applied electric (E-)fields on the skyrmion lattice in the chiral lattice magnetoelectric Cu(2)OSeO(3). Using an experimental geometry with the E-field parallel to the [111] axis, and the magnetic field parallel to the [11(-)0] axis, we demonstrate that the effect of applying an E-field is to controllably rotate the skyr...
متن کاملElectric-field induced pK-changes in bacteriorhodopsin.
Bacteriorhodopsin, the only protein of the purple membranes of halobacteria [ 11, acts as a light-driven proton pump, translocating protons from the inner to the outer side of the plasma membrane [2]. The lightinduced asymmetric proton distribution contributes to the membrane potential by up to lo-40 mV [3]. Assuming a membrane thickness of 50 A, this potential difference corresponds to an elec...
متن کاملElectric Field-induced Structural Rearrangements in Biomembranes
Structure and function of biological membranes are vitally dependent on the electric membrane polarization; prolonged depolarization of the plasma membrane causes cell death. The natural cross-membrane electric field affecting the protein/lipid dielectrics are on the order of 100 kVcm_ t. The inhomogeneous field originating from ionic groups and adsorbed small ions are of the same order of magn...
متن کاملElectric-Field-Induced Triplet to Singlet Transition in Size-2 Trigonal Zigzag Graphene Nanoflake
Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...
