In ferrite–piezoelectric bilayers, the magnetoelectric (ME) interaction is mediated by mechanical strain. The ME coupling is expected to be strong, particularly when the magnetic and electric subsystems show resonance. Here we address the effect of magnetic exchange interactions on ME coupling at magnetoacoustic resonance (MAR), i.e., at the coincidence of electromechanical resonance in the piezoelectric phase and ferromagnetic resonance in a tangentially magnetized ferrite. When exchange is ignored, the estimated ME coefficient versus frequency profile shows a giant magnetoelectric coefficient at MAR, about 75–100 V/cm Oe for yttrium–iron garnet (YIG)/lead zirconate–titanate (PZT) nano bilayers. The magnetic exchange is predicted to enhance the coupling at MAR and produce a secondary peak due to the excitation of magnetoacoustic modes. Estimates of the ME coefficient are provided as a function of thickness ratio of YIG and PZT.

The exsolution of magnetite from a substituted Yttrium Iron Garnet, containing an iron excess may lead to a transitional event. This event is characterized hy the formation of a transitional zone at the center of which the magnetite nucleates (Fig.1). Since there is a contrast between the matrix and these zones and since selected area diffraction does not show any difference between those zones and the matrix in the reciprocal lattice, it is of interest to analyze the structure of the transitional zones.By using simultaneously different techniques in electron microscopy, (oscillating crystal method microdiffraction and X-ray microanalysis)one may resolve the ionic process corresponding to the transitional event and image this event subsequently by high resolution technique.

Titanate Ceramics

Lead zirconate titanate, Pb(Zr,Ti)O3 (PZT), ceramics are ferroelectrics formed as solid solutions between ferroelectric PbTiO3 and ant iferroelectric PbZrO3. The subsolidus phase diagram is shown in figure 1. PZT transforms between the Ti-rich tetragonal (T) and the Zr-rich rhombohedral (R) phases at a composition which is nearly independent of temperature. This phenomenon is called morphotropism, and the boundary between the two phases is known as the morphotropic phase boundary (MPB). The excellent piezoelectric and dielectric properties occurring at this composition are believed to.be due to the coexistence of T and R phases, which results in easy poling (i.e. orientation of individual grain polarizations in the direction of an applied electric field). However, there is little direct proof of the coexistence of the two phases at the MPB, possibly because of the difficulty of distinguishing between them. In this investigation a CBD method was found which would successfully differentiate between the phases, and this was applied to confirm the coexistence of the two phases.
