Magnetoelectric Multiferroic Composites
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...
متن کاملHigh-sensitivity piezoelectric perovskites for magnetoelectric composites
A highly topical set of perovskite oxides are high-sensitivity piezoelectric ones, among which Pb(Zr,Ti)O3 at the morphotropic phase boundary (MPB) between ferroelectric rhombohedral and tetragonal polymorphic phases is reckoned a case study. Piezoelectric ceramics are used in a wide range of mature, electromechanical transduction technologies like piezoelectric sensors, actuators and ultrasoun...
متن کاملResistivity, Thermoelectric Power and Magnetoelectric Effect in Ni0.7Co0.3Fe2O4 + Ba0.7Pb0.3TiO3 Composites
(y)Ni0.7Co0.3Fe2O4 + (1-y) Ba0.7Pb0.3TiO3 composites were prepared using ceramic method. The phase analysis was carried out by X-ray diffraction technique. It has confirmed that no impurity phase is present in the composites. The dc resistivity, thermo emf studied as a function of temperature. The value of static magnetoelectric conversion factor, i.e. dc (ME)H studied as a function of magnetic...
متن کاملElectromechanical resonance in multilayer and bulk magnetoelectric composites
Magnetic photonic crystals are spatially periodic dielectric composites with at least one of the constitutive components being a magnetically polarized material. We show that the electrodynamic properties of magnetic photonic crystals with proper configuration correspond to those of hypothetical media with huge linear magnetoelectric effect. In particular, such composites can display strong asy...
متن کاملPredicting Magnetoelectric Coupling in Layered and Graded Composites
Magnetoelectric (ME) interaction in magnetostrictive-piezoelectric multiferroic structures consists in inducing the electric field across the structure in an applied magnetic field and is a product property of magnetostriction and piezoelectricity in components. ME voltage coefficient that is the ratio of induced electric field to applied magnetic field is the key parameter of ME coupling stren...
