Magnetoelectric (ME) multiferroics are materials in which ferromagnetism and ferroelectricity occur simultaneously and coupling between the two is enabled. Applied magnetic field H gives rise to an induced polarization P which can be expressed in terms of magnetic field by the expression, P=┙H, where ┙ is the ME-susceptibility tensor. Most of the known single-phase ME materials are known to sho...

A miniaturized arrangement based on magnetostrictive delay line (MDL) mechanism, able to be used as sensor, is realized using thin films technology. In order to obtain high-performance miniaturized magnetostrictive delay line arrangement we used Fe, Ni and Fe70B20Si6C4 amorphous thin films as magnetostrictive sensing element because of their better magnetic and magnetoelastic characteristics th...

Understanding strain gradient phenomena is of paramount importance in diverse areas condensed matter physics. This effect responsible for flexoelectricity dielectric materials, and it plays a crucial role the mechanical behavior nanoscale-sized specimens. In magnetoelectric composites, which comprise piezoelectric or ferroelectric (FE) materials coupled to magnetostrictive (MS) phases, can add ...

We report an enhanced magnetoelectric (ME) effect in a heterostructure consisting of a long-type, longitudinally-longitudinally polarized 0.71Pb(Mg(1∕3)Nb(2∕3))O(3)-0.29PbTiO(3) (PMN-PT) piezoelectric single-crystal transformer with its input part sandwiched between two longitudinally magnetized Tb(0.3)Dy(0.7)Fe(1.92) (Terfenol-D) magnetostrictive alloy bars. The observed ME effect has two inde...

We have measured electromagnetic energy harvesting properties of all-thin-film magnetoelectric (ME) heterostructures on Si cantilevers. The devices are built on a silicon oxide/nitride/oxide stack, and the ME layers consist of a magnetostrictive Fe0.7Ga0.3 thin film and a Pb(Zr0.52Ti0.48)O3 piezoelectric thin film. The harvested peak power at 1 Oe is 0.7 mW/cm (RMS) at the resonant frequency (3...

Single-phase magnetoelectric multiferroics are ferroelectric materials that display some form of magnetism. In addition, magnetic and ferroelectric order parameters are not independent of one another. Thus, the application of either an electric or magnetic field simultaneously alters both the electrical dipole configuration and the magnetic state of the material. The technological possibilities...

Magnetoelectric composite thin films hold substantial promise for applications in novel multifunctional devices. However, there are presently shortcomings for both the extensively studied bilayer epitaxial (2-2) and vertically architectured nanocomposite (1-3) film systems, restricting their applications. Here we design a novel growth strategy to fabricate an architectured nanocomposite heteros...
