Multilayered ceramic heterostructures of lead zirconate titanate and nickel-zinc ferrite for magnetoelectric sensor elements

- The results of magnetoelectric effect studies in multilayered ceramic heterostructures are presented in this paper.
- The maximum value of a magnetoelectric voltage coefficient αE=35 V/(cm·Oe) was observed for the eleven-layered rectangular specimen at the electromechanical resonance frequency fr = 144 kHz, НDC = 84 Oe, and НAC = 2.5 Oe.
- The sensitivity to static magnetic fields is equal to 3.5·10−2 Oe, and the alternating field sensitivity is equal to 8·10−3 Oe.

The preparation method of magnetoelectric multilayered ceramic heterostructures was suggested, and series of the rectangular and disk shape samples were produced on the base of this method. The maximum value of a magnetoelectric voltage coefficient αE = 35 V/(cm × Oe) was observed for the eleven-layered rectangular specimen at the electromechanical resonance frequency fr = 144 kHz, НDC = 84 Oe, and НAC = 2.5 Oe. The sensitivity to static magnetic fields is equal to 3.5 × 10−2 Oe, and the alternating field sensitivity is equal to 8 × 10−3 Oe.
