Simple model of the magnetoelectric effect in layered cylindrical composites
نویسندگان
چکیده
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 two directions simultaneously, one along the thickness direction (normal, t) and the other along the effective height (tangential, Leff ) direction, respectively. Experimental results and theoretical analysis indicated that the cylindrical layered composites ME voltage coefficient is much higher compared with that of the layered plate.

Resonant modes and magnetoelectric performance of PZT/Ni cylindrical layered composites
Resonant modes and magnetoelectric performance of layered PZT/Ni and Ni/PZT/Ni cylindrical composites are considered. The first and the second resonant frequencies in the 1–150 kHz range correspond to the axial and the radial modes. Experimental results and theoretical analysis indicate that one should choose the trilayered structure and the first resonant frequency as the working frequency. Th...

This paper presents the magnetoelectric (ME) effect in trilayered Ni/PZT/Ni composites which is related to their size and shape. The ME composites with the same interfacial areas but different geometrical shapes have different ME voltage coefficients. Longitudinal resonant modes in the rectangular and triangular trilayered ME composites were studied. One should choose optimized size, shape and ...
متن کاملElectro-deposition current density effect on Ni/PZT layered magnetoelectric composites performance
This paper considers the magnetoelectric (ME) effect in Ni/PZT layered ME composites that is related to the preferred crystallographic orientation of electro-deposited Ni layers. The Ni electro-deposition rate increases with applied cathodic current density. High (1 0 0) texture in the Ni layer was obtained at either low or high current densities, which improves the ME composite’s performance. ...

Introduction: The acoustic performance of natural fiber adsorbents has been investigated in numerous studies. A part of these materials show a poor adsorption within the frequency range of less than 1000 Hz. In the present study, attempts were made to investigate the effect of layout sequence of double-layered composites consisting of natural and synthetic fibers on improving the acoustic adsor...
