Giant magnetoelectric effect in Ni–lead zirconium titanate cylindrical structure

Abstract

The magnetoelectric (ME) coupling of a bilayered Ni–lead zirconate titanate composite structure synthesized by electrodeposition was studied in this paper. The ME voltage coefficient was measured in the range of 1–120kHz as the bias field is parallel to the axial. The results indicate that an electromechanical resonance appears at 59.9kHz. The bilayered cylindrical ME composite exhibits a special field dependence of ME coefficient. Either for the resonant state or the nonresonant state, above 1kOe, the ME voltage coefficient increased linearly with the strengthening of bias field, up to 30V∕cmOe at 8kOe.

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

“…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.…”

“…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.…”

“…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].…”

“…10 On the other hand, some specific multilayer composites have been developed, and their DME resonance characteristics have been studied under the influence of magnetic fields. [12][13][14][15][16] Compared to the DME effect, studies on the CME effect are obviously few, especially on the resonance CME effect. In fact, developing a laminated composite showing a high CME effect is an increasingly important topic for promoting coil-free electromagnetism and the related device physics.…”

“…1 Since the first observation of the DME and CME effects in Cr 2 O 3 antiferromagnetic single crystal in the early 1960s, 2 a variety of ME materials have been discovered or developed for potential applications in power-free magnetic field/electric current sensors or ME transducers based on the DME effect. [3][4][5][6][7][8][9][10][11][12][13][14][15][16] These materials can generally be classified as single-phase and multiphase materials. Single-phase materials have both ferroelectric order and ferromagnetic (or antiferromagnetic) order in the same phase, thus enabling an electric field switchable spontaneous polarization, a magnetic field switchable spontaneous magnetization, and often some coupling between the two.…”
