Nonlinear electric field tuning characteristics of yttrium iron garnet–lead zirconate titanate microwave resonators

Abstract: This report is on hysteresis and switching associated with electric field (E) tuning of ferromagnetic resonance in a bilayer of yttrium iron garnet (YIG)-lead zirconate titanate (PZT). The tuning is facilitated by piezoelectricity of PZT and mechanical bonding with YIG. For E 10kV∕cm, a butterflylike dependence of δf with an abrupt switch in the sign and magnitude of δf are measured. The observations are attributed to nonlinearities of the piezoelectric deformation.

Polarization Orientation in Lead Zirconate Titanate (001) Thin Films Driven by the Interface with the Substrate

Abstract: The orientation of polarization in ferroelectric thin films is important for applications of these materials in nonvolatile memory and field-effect transistors with ferroelectric gates, and in catalysis and photocatalysis. One means of control is to choose a well defined substrate, but the influence of a substrate's electronic properties on polarization orientation is not well understood. In this investigation of model systems, the experimental findings are integrated with electrostatic models to determine the magnitudes and orientations of the interfacial electric fields that are useful for setting the polarization of the thin ferroelectric epilayer.

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

Abstract: Magnetoelectric (ME) coupling of a cylindrical trilayered composite was studied in this paper. A Ni?lead zirconate titanate (PZT)-Ni trilayered cylindrical composite was synthesized by electro-deposition. The maximum ME voltage coefficient of the cylindrical ME composite is 35?V?cm?1?Oe?1, 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 the cylindrical composite is due to the self-bound effect of the circle. Moreover, the resulting complex condition can induce a double peak in the field dependence of the ME coefficient.

P2E-3 Power Harvesting Using Piezoelectric MEMS Generator with Interdigital Electrodes

Abstract: The energy harvesting from ambiance to power the tiny sensor devices by MEMS generator is becoming practical due to the power consumption of low power VLSI (very large scale integration) circuits is going down to tens to hundreds muW for integrated wireless sensor devices. In this paper, we present the design and process development of a piezoelectric MEMS generator that has the ability to scavenge mechanical energy of ambient vibrations and transform it into electrical energy. The piezoelectric MEMS generator comprises a beam structure based on the silicon wafer with laminated PZT (lead zirconate titanate) material and interdigital electrodes on the top of the PZT layer, to transform mechanical strain energy into electrical charge using the d33 mode of PZT. An in-house developed PZT deposition chamber which could deposit PZT thin film up to tens micron in minutes was used to deposit the piezoelectric layer on the beam structure of the piezoelectric MEMS generator. The output power performance and output voltage with varied gaps of the interdigital electrodes are evaluated and detailed in this paper.
