Magnetoelectric (ME) composites that simultaneously exhibit ferroelectricity and ferromagnetism have recently gained significant attention as evident by the increasing number of publications. These research activities are direct results of the fact that multiferroic magnetoelectrics offer significant technological promise for multiple devices. Appropriate choice of phases with co-firing capabil...

Films of the composition Ba 0.8 Sr 0.2 TiO 3 (BST) were synthesized by method high-frequency (HF) sputtering on buffer layer a ferroelectric film PbZr x Ti 1-x O (PZT). Comparative results electrophysical properties three different metal--dielectric--metal (MDM)-structures are presented: Pt/BST/Ni, Pt/PZT/Ni, and Pt/PZT-BST/Ni. Keywords: structures, films , layer, properties.

The thin-film x-ray standing wave ~XSW! technique is used for an atomic-scale study of polarization switching in ferroelectric Pb~Zr0.3Ti0.7!O3 ~PZT!/electrode heterostructures grown on SrTiO3(001). The XSW is selectively generated in the PZT by the interference between the incident x-ray wave and the weak ~001! Bragg diffracted wave from the film. The XSW excites a fluorescence signal from the...

It is also being explored for new applications such as nanorods, [ 9 ] domain physics, [ 10 ] and nanodevices. [ 11,12 ] Transfer of PZT thin fi lms can allow integration of such fi lms on substrates that are incompatible with the requirements of fi lm deposition. However, transfer of functional ceramic thin fi lms has long been hampered by the diffi culty of detaching the fi lm from the growth...

Cavity ring-down spectrometers typically employ a PZT stack to modulate the cavity transmission spectrum. While PZTs ease instrument complexity and aid measurement sensitivity, PZT hysteresis hinders the implementation of cavity-length-stabilized, data-acquisition routines. Once the cavity length is stabilized, the cavity's free spectral range imparts extreme linearity and precision to the meas...

Lead zirconate titanate (PZT) thick films with uniformly dispersed submicrometer pores were successfully fabricated on platinized silicon substrates with various thicknesses ranging from 1 lm to over 100 lm by aerosol deposition. Mixed powders of PZT and polyvinylidene fluoride (PVDF) were deposited for initial fabrication of composite films. After burn-out of the PVDF phase from the composite ...

This paper relates to vibration control using passive electrical shunt circuits. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate (PZT) piezoelectric ceramic material. The problem is further complicated by the material composition of the substrate or host material the PZT is coupled to. ...

We study, on an atomic scale, the influence of a single dislocation in a SrTiO3 sublayer on the local ferroelectric polarization of the neighboring ferroelectric PbZr0.2Ti0.8O3 (PZT) sublayer in an epitaxial SrTiO3/PbZr0.2Ti0.8O3/SrTiO3 three-layer heterostructure. The strain field of the dislocation in the SrTiO3 layer propagates across the interface into the PZT layer and leads to a strong va...

This paper reports on conception, simulation, and fabrication of a lead zirconate titanate (PZT) MEMS cantilevers for piezoelectric energy harvesting (EH). We investigate the advantages of interdigitated electrode configurations (IDE) with respect to parallel-plate electrodes (PPE) in terms of output voltage and output power from the constitutive equations of piezoelectricity. Finite element mo...

Lead Zirconate Titanate, PZT, layered into a composite with different materials, produces pre-stressed, curved, devices capable of enhanced displacement. This study focuses on Thunder and Lipca which are built using different combinations of constituent materials. Thunder devices consist of layers of aluminum, PZT, and stainless steel bonded with a hot-melt adhesive. Lipca devices consist of ca...
