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.

Voltage Coefficient

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.

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.

The Relationship

A giant magnetostrictive actuator is designed with strong bias magnetic field. The influence of the strong bias field is introduced, and the corresponding exciting input signal is selected. Magnetic reluctance estimation, approximate linearity between the strain and magnetic field, and a mass–spring–damper system assumption are employed to analyze the actuator’s displacement with low-frequency signal input. An experimental system is designed, and properties of the proposed actuator are tested. With the help of square wave test, appropriate direction of exciting signal for the magnetostrictive actuator is determined. With the help of sinusoidal wave test, the established model is validated and the relationship between the maximum value of the displacement and of the current is analyzed. With exciting frequency lower than 200 Hz, the errors between the calculating and testing results are within 1.0 m, which validates the model.

The effects of AC frequency, magnetic field strength, ribbon length and test temperature on the Fe72Co8Si15B5 amorphous ribbon’s magnetic impedance were studied. The results showed that the resistance, reactance and impedance of amorphous ribbons increased with the increase of AC frequency, but decreased as magnetic field strength decreased; the rangeability of resistance, reactance and impedance increased as AC frequency and magnetic field strength increased; the resistance and reactance increased as ribbon length increased; the ribbon had a good temperature stability in resistance.

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.
