Control of Topological Magnetic Textures by Magnetic and Electric Fields in Magnetoelectric Helimagnet Cu₂OSeO₃

Ping Huang

Magnetic skyrmions, topologically non-trivial chiral whirl-like spin configurations, have been under massive investigations in both fundamental and application aspects. In some special compounds, these quasi-particles can formtriangular skrymion lattice (S ...

Heuristic Description of Magnetoelectricity of Cu2OSeO3

Helmuth Berger

CuO2SeO3 is an insulating material that hosts topologically nontrivial spin whirls, so-called skyrmions, and exhibits magnetoelectric coupling allowing to manipulate these skyrmions by means of electric fields. We report magnetic force microscopy imaging o ...

It is generally accepted that nuclear quantum effects (NQEs) trigger the transition to the nonmolecular form of ice under increasing pressure. This picture is challenged in salty ice, where Raman scattering measurements up to 130 GPa of molecular ice VII c ...

Charged domain walls in proper ferroelectrics were shown recently to possess metallic-like conductivity. Unlike conventional heterointerfaces, these walls can be displaced inside a dielectric by an electric field, which is of interest for future electronic ...

This article discusses technical issues related to compliance assessment of ICNIRP 2010 basic restrictions. Several difficulties are identified in this study when assessing the spatial average and 99th percentile value of the electric field. These issues a ...

Stretching cells with DEAs

Herbert Shea, Samuel Rosset, Samin Akbari

Biological cells regulate their biochemical behavior in response to mechanical stress present in their organism. Most of the available cell cultures designed to study the effect of mechanical stimuli on cells are cm2 area, far too large to monitor single c ...

Positive effective Q(12) electrostrictive coefficient in perovskites

Alexander Tagantsev, Alexander Kvasov

It is demonstrated that for classical perovskites, such as BaTiO3; SrTiO3, and PbTiO3, electrostrictive strain induced by an electric field may not obey traditionally considered "extension along the field and contraction perpendicular to it" behavior if th ...

Accurate and versatile modeling of electromagnetic scattering on periodic nanostructures with a surface integral approach

Olivier Martin, Benjamin Gallinet, Andreas Kern

A surface integral formulation for light scattering on periodic structures is presented. Electric and magnetic field equations are derived on the scatterers' surfaces in the unit cell with periodic boundary conditions. The solution is calculated with the m ...

Experimental Measurement of Monovalent Cation Adsorption onto Bacillus subtilis Cells

Daniel Scott Alessi

Typically, the effects of ionic strength on metal adsorption to geosorbents are accounted for by models of the surface electric field, assuming a planar surface. However, bacterial cell walls are not two-dimensional surfaces. Furthermore, electric field mo ...

Electromagnetic Scattering of Finite and Infinite 3D Lattices in Polarizable Backgrounds

Olivier Martin, Benjamin Gallinet

A novel method is elaborated for the electromagnetic scattering from periodical arrays of scatterers embedded in a polarizable background. A dyadic periodic Green's function is introduced to calculate the scattered electric field in a lattice of dielectric ...
