Topological transition from a hopfion to a toron via flexoelectric self-polarization in chiral liquid crystals

Physical Review Research
The presence of topological defects in apolar chiral liquid crystals causes orientational distortions, leading to nonuniform strain. This nonuniform strain generates an electric polarization response due to the flexoelectric effect, which induces an ...

Magnetostatic waves in the gap between two ferromagnetic with longitudinal magnetizations that move relative to each other

Физика волновых процессов и радиотехнические системы, 2013
The propagation of a magnetostatic gap wave in a gap between two ferromagnetic with opposite longitudinal magnetizations is considered under the conditions for relative longitudinal displacement.

Metallography Investigation of Thermal Wave Control by Magneto-Static Field [PDF]

Journal of Optoelectronical Nanostructures, 2018
In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms.

On the single field formulation in magnetostatics

We systematically discuss the equivalence of two variational formulations of magnetostatics, in terms of magnetization and magnetic field on the one hand and the single field formulation using only magnetic induction. To demonstrate that this link is stable also when the magnetic laws are coupled with other variational static models, elasticity is ...

Low computational cost semi-analytical magnetostatic model for magnetocaloric refrigeration systems

AIP Advances, 2018
The analysis of the active magnetic refrigeration (AMR) cycle for different waveforms of both the magnetic field and the velocity of the heat transfer fluid is an essential challenge in designing and implementing heating and cooling systems based on the ...

Collective magnetism in arrays of spinor Bose–Einstein condensates

New Journal of Physics, 2013
We elucidate dipolar magnetic interaction effects in spinor condensates at a low-background field. In particular, we show that arrays of ferromagnetic spinor Bose–Einstein condensates show a rich phase structure that is strongly influenced by the ...
