Resonance magnetoelectric effect analysis and output power optimization of a nonlinear magnetoelectric transducer model

Topological magnetoelectric effect decay.

We address the influence of realistic disorder and finite doping on the effective magnetic monopole induced near the surface of an ideal topological insulator (TI) by currents that flow in response to a suddenly introduced external electric charge. We show that when the longitudinal conductivity σ(xx)=g(e(2)/h)≠0, the apparent position of a magnetic monopole initially retreats from the TI surfa...

Resistivity, Thermoelectric Power and Magnetoelectric Effect in Ni0.7Co0.3Fe2O4 + Ba0.7Pb0.3TiO3 Composites

(y)Ni0.7Co0.3Fe2O4 + (1-y) Ba0.7Pb0.3TiO3 composites were prepared using ceramic method. The phase analysis was carried out by X-ray diffraction technique. It has confirmed that no impurity phase is present in the composites. The dc resistivity, thermo emf studied as a function of temperature. The value of static magnetoelectric conversion factor, i.e. dc (ME)H studied as a function of magnetic...

Inductance–capacitance resonance effect in the magnetoelectric composites characterization system

This paper presents the inductance–capacitance (LC) resonance effect in the magnetoelectric (ME) composites characterization system. The measured magnetoelectric voltage coefficient is significantly affected by the LC resonance at the electromechanical resonant frequency, but not at 1 kHz, typically reported in the literature. Decreasing the measuring circuit inductance and/or capacitance helps...

Simple model of the magnetoelectric effect in layered cylindrical composites

A simple model of the magnetoelectric (ME) effect in cylindrical layered composites is presented. The cylinder is replaced by the effective layered plate structure with effective length, Leff , thickness t and height h. In the axial coupling mode, the effective magnetic field acts along the length direction (Leff ). However, in the vertical coupling mode, the effective magnetic fields act in tw...
