Magnetoelectric effect in a Ni–PZT–Ni cylindrical layered composite synthesized by electro-deposition

Abstract

The magnetoelectric (ME) coupling of cylindrical trilayered composite was studied in this paper. The Ni-lead zirconate titanate (PZT)-Ni trilayered cylindrical composite was synthesized by electro-deposition. The maximum ME voltage coefficient of cylindrical ME composite is 35V/cm Oe, about three times higher than that of the plate trilayered composite with the same raw materials and magnetostrictive-piezoelectric phase thickness ratio. The high ME voltage coefficient of cylindrical composite owes to the self-bound effect of circle. Moreover, the resulting complex condition can induce a double peak in the field dependence of ME coefficient.

Resonant modes and magnetoelectric performance of PZT/Ni cylindrical layered composites

“…The ME voltage coefficients α E initially increased and then decreased subsequently with H DC at negative magnetic field when the applied frequency was 1 kHz for bilayered and trilayered samples. With H DC increasing continuously, the α E trend for both samples is the same as reported in the previous work [10]. However, there appear two peaks in the H DC curve in the vertical mode at positive fields.…”

“…Then, the PZT cylinder was bathed in nickel aminosulfonate plating solution to electro-deposit the Ni layer. The composition of the plating solution is described in detail elsewhere [8][9][10][11]. For the PZT/Ni bilayered structure, after the cylinder inner wall was protected by the silicone rubber, only the outer surface Ni electrode was deposited.…”

“…For the Ni/PZT/Ni trilayered structure, Ni was electro-deposited on Fig. 1 A schematic diagram for (a) trilayered and (b) bilayered hollow cylindrical layered composite structures and (c) clamp [10]. Here, d 31 and d 33 are the piezoelectric constants of the PZT cylinder both hollow cylinder sides.…”

“…In previous studies plate and cylindrical layered ME composites made by electro-deposition were considered [8][9][10][11]. Electrodeposited plate layered ME composites have comparable ME performance to the Terfenol-D/PZT prepared by the gluing method [8,9].…”

“…Electrodeposited plate layered ME composites have comparable ME performance to the Terfenol-D/PZT prepared by the gluing method [8,9]. Nickel (Ni)/lead zirconate titanate (PZT)/Ni trilayered composites also have some novel ME properties [10], while cylindrical Ni/PZT bilayered composites exhibit high gain ME effect at resonant frequency under high magnetic field induced by the volume magnetostriction and possibly induction effects [11]. Cylindrical layered ME composites have a significant potential for applications in high magnetic field detection.…”
