“…Suchtelen et al [3] suggested the realization of composites of piezoelectric and magnetostrictive phases which could be electromagnetically coupled via stress mediation. Various groups have therefore, focused efforts on realization of bulk composites or heterostructural layers [4][5][6][7]. However, it is important to note that the structural non-compatibility and reactivity between two materials and also with the substrate, generates immense difficulties in growing heterostructures and achieving coupling between the two order parameters.…”

The coexistence of ferroelectric and ferromagnetic properties at room temperature is very rarely observed. We have been successful in converting ferroelectric PbTiO 3 into a magnetoelectric material by partly substituting Fe at the Ti site. The Pb(Fe 1-x Ti x )O 3 system exhibits ferroelectric and ferromagnetic ordering at room temperature. Even more remarkably, our results demonstrate a coupling between the two order parameters. Hence it could be a futuristic material to provide cost effective and simple path for designing novel electromagnetic devices. 74.25.Ha; PACS:

“…The corresponding ME coefficients YIG/PZT structure extracted from magnetostriction-induced magnetic field shifts are α1 = δH1/δE ≈ 0.58 Oe·cm/kV and α2 = δH2/δE ≈ 0.88 Oe·cm/kV (δH is the ferromagnetic resonance shift due to an applied electric field δE), for magnetic-bias field applied parallel and perpendicular to the sample plane, respectively, which are comparable to 1-4 Oe·cm/kV measured in similar YIG/ PZT bilayers [4]. The range of the frequency tuned by electric field could potentially be increased by either decreasing the thickness of the GGG substrate or by using a ferroelectric with higher piezoelectric coefficients, such as single-crystal PMN-PT.…”

Tunable microwave magnetoelectric devices based on layered ferrite-ferroelectric structures are described. The theory and experiment for attenuator, band-pass filter and phase shifter are presented. Tunability of the ME devices characteristics can be executed by application of an electric field. This electric tuning is relatively fast and is not power-consuming. The attenuator insertion losses vary from 26 dB to 2 dB at frequency 7251 MHz. The tuning range of 25 MHz of band-pass filter at frequency 7360 MHz was obtained. A maximum phase shift of 30-40 degree at the frequency region 6-9 GHz was obtained.

“…Next we consider specific composites and estimate the magnetic susceptibility and its electric field variation. (Bichurin et al, 2002) Figure 5 shows the static magnetic field dependencies of real and imaginary parts of magnetic susceptibility for layered LFO-PZT, NFO-PZT and YIG -PZT. The results are for a bilayer disk sample with the H and E-fields perpendicular to the sample plane and for a frequency of 9.3 GHz.…”
