Interface magnetoelectric effect in elastically linked Co/PZT/Co layered structures

Titanium-based alloys are widely used in aerospace engineering. They have good mechanical and corrosion properties but, in some cases, the material itself or the coating should meet some additional requirements. For example, it may be a requirement of high reflectance to provide effective temperature control. Wollastonite is a promising component for reflective coatings because it improves both their whiteness and mechanical properties. This paper presents the results of studying the composition, the structure and the adhesive strength of wollastonite-containing silicate coatings to titanium substrate. The surface of titanium samples was pre-treated by laser cladding with TiC and etching to provide surface porosity. It has been shown that such treatment allows a significantly increase in the adhesive strength of the coating to the substrate. A decrease in the adhesive strength was observed on titanium samples with an excess of TiO2 on the surface. This is caused by the formation of crystalline PbTiO3 at the interface.

In the layered ferromagnetic /ferroelectric structures in the form of cobalt, nickel or permendur layer on a ferroelectric substrate of lead zirconate titanate obtained by ion-beam sputtering – deposi-tion, relative strains due to mismatch of crystal lattices of mating materials at the metal / substrate in-terface make a more noticeable contribution to the magnetoelectric response than those associated both with the magnetostriction of the ferromagnetic layer and with the piezoelectric effect of the fer-roelectric substrate. The structures obtained are characterized by the thermal stability and reproduci-bility of magnetoelectric characteristics and can be used as converters of magnetic and electrical quantities, for example, in magnetic field sensors and actuators.

“…Multiferroics are the substances with two or more ‘ferro’ properties (ferromagnetic, ferroelectric, ferroelastic), integrated in a single entity. Among other new smart materials, they are extensively studied due to their wide prospects in sensing and energy transforming and harvesting techniques [ 1 , 2 , 3 ] since such working elements are enticing due to their ability to operate in wide frequency, field, temperature, etc., ranges [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. The point of highest interest in multiferroics is their ability to perform magnetoelectric conversion.…”

“…The magnetoelectric effect (MEE) in composite multiferroics exceeds this effect in natural multiferroic materials [ 4 ]. The highest values of MEE are obtained on solid composite multiferroics, e.g., layered materials or nanocomposites, which comprise both magnetostrictive and electrostrictive (piezoelectric) phases [ 5 , 6 ]. An instructive example is a composite that consists of a closely-packed and sintered mixture of ferromagnetic (FM) and ferroelectric (FE) grains.…”

Multiferroic Coupling of Ferromagnetic and Ferroelectric Particles through Elastic Polymers

Multiferroics are materials that electrically polarize when subjected to a magnetic field and magnetize under the action of an electric field. In composites, the multiferroic effect is achieved by mixing of ferromagnetic (FM) and ferroelectric (FE) particles. The FM particles are prone to magnetostriction (field-induced deformation), whereas the FE particles display piezoelectricity (electrically polarize under mechanical stress). In solid composites, where the FM and FE grains are in tight contact, the combination of these effects directly leads to multiferroic behavior. In the present work, we considered the FM/FE composites with soft polymer bases, where the particles of alternative kinds are remote from one another. In these systems, the multiferroic coupling is different and more complicated in comparison with the solid ones as it is essentially mediated by an electromagnetically neutral matrix. When either of the fields, magnetic or electric, acts on the ‘akin’ particles (FM or FE) it causes their displacement and by that perturbs the particle elastic environments. The induced mechanical stresses spread over the matrix and inevitably affect the particles of an alternative kind. Therefore, magnetization causes an electric response (due to the piezoeffect in FE) whereas electric polarization might entail a magnetic response (due to the magnetostriction effect in FM). A numerical model accounting for the multiferroic behavior of a polymer composite of the above-described type is proposed and confirmed experimentally on a polymer-based dispersion of iron and lead zirconate micron-size particles.
