A 1200m V/cmOe magnetoelectric voltage coefficient was measured in a Terfenol-D/epoxy and PZT-5H[2-2] composite. The magnetoelectric effect is a result of a coupling between the magnetostrictive (Terfenol-D/epoxy) and piezoelectric (PZT-5H) layers. The coupling was achieved mechanically by bonding the piezoelectric layer in between two magnetostrictive layers. The maximum in magnetoelectric voltage coefficient was measured at a frequency of 8Hz and a bias magnetic field of 103kA/m. The magnetoelectric voltage coefficient was observed to be highly dependent upon the bias magnetic field.

Laminate Materials

Magnetoelectric(ME) effect in magnetoelectric laminate materials have potential application in many fields. In this paper, Fe78Si9B13 amorphous ribbons /PZT/amorphous ribbons sandwich structure laminate materials were fabricated. By theoretical analysis and experimental verification, we studied systemically on the characteristics of the magnetoelecric laminate materials, such as optimized bias magnetic field of the ME effect, ME voltage coefficient at low frequency and the resonant frequency of the magnetoelecric laminate element. ME effect can be used to develop new ac magnetic sensor and other devices.

Magnetoelectric Coefficient

Magnetoelectric anisotropy was researched in a disc laminate composite. The magnetoelectric coefficient exhibits a cosine characteristic with the angle between the direction of dc bias magnetic field [Formula: see text] and small ac sine magnetic signal [Formula: see text], no matter how [Formula: see text] rotates. Correspondingly, there are only two values of phase shift when the angle varies from 0 to 360[Formula: see text]. These two phase shifts only depend on [Formula: see text] mapping on [Formula: see text], i.e., sign of dot product of [Formula: see text] and [Formula: see text] [Sgn([Formula: see text])], implying that [Formula: see text]cos[Formula: see text] produces charge through the magnetoelectric effect. Then, a simple device was proposed to detect the magnitude and direction of ac magnetic field.

Double Frequency

Parametric amplification of magnetoacoustic oscillations was observed in a disk resonator containing a ferromagnetic layer of FeBSiC and a piezoelectric layer of lead zirconate-titanate. Oscillations with a frequency of 3.08 kHz were excited and recorded using two coils with orthogonal axes. Pumping was performed by an electric field with a double frequency applied to the piezoelectric layer. The amplification of vibrations arises due to a change in the rigidity of the structure under influence of an electric field. It is shown that the gain can be changed using a permanent bias magnetic field applied to the structure.

Working Characteristic

The article is devoted to the theoretical and experimental study of a magnetoelectric (ME) current sensor based on a gradient structure. It is known that the use of gradient structures in magnetostrictive-piezoelectric composites makes it possible to create a self-biased structure by replacing an external magnetic field with an internal one, which significantly reduces the weight, power consumption and dimensions of the device. Current sensors based on a gradient bidomain structure LiNbO3 (LN)/Ni/Metglas with the following layer thicknesses: lithium niobate—500 μm, nickel—10 μm, Metglas—29 μm, operate on a linear section of the working characteristic and do not require the bias magnetic field. The main characteristics of a contactless ME current sensor: its current range measures up to 10 A, it has a sensitivity of 0.9 V/A, its current consumption is not more than 2.5 mA, and its linearity is maintained to an accuracy of 99.8%. Some additional advantages of a bidomain lithium niobate-based current sensor are the increased sensitivity of the device due to the use of the bending mode in the electromechanical resonance region and the absence of a lead component in the device.

The Magnetic Field

We investigate the magnetic-field-orientation dependent magnetoelectric (ME) effect in the FeBSiC/Pb(Zr,Ti)O3(PZT)/FeBSiC laminates. It is shown that, by only using the bias-magnetic-field dependent ME response measured with the magnetic-field parallel to the surface plane of PZT slab, the magnetic-field-orientation dependent ME coefficient upon magnetic-fields of various amplitudes can be obtained via computer simulations. The simulation results match well the experimental measurements, demonstrating the applicability of the ME laminates-based sensors in detecting magnetic-fields with uncertain amplitudes and/or orientations in environment.

The results of the magnetoelectric effect study in the magnetopiezofiber are presented. Magnetopiezofiber consists of mechanically coupled piezoelectric (one layer of lead zirconate titanate) and magnetostrictive (two metglass layers) fibers. The layers were joined together by epoxy under pressure and heating. The sample active area dimensions were 28x7x0,34 mm. The study of the magnetoelectric effect was carried out in the frequency range from 0 to 150 kHz and external magnetic field range from 0 to 100 Oe. Maximum value of the ME voltage coefficient αE = 62,75 V/cm-Oe was measured on the electromechanical resonance frequency f = 61 kHz with an external magnetic field of 4,5 Oe. Obtained results indicate the prospects of the proposed design in magnetoelectric devices application.
