A theory of voltage-induced control magnetic domain walls propagating along the major axis a magnetostrictive nanostrip, tightly coupled with ceramic piezoelectric, is developed in framework Landau–Lifshitz–Gilbert equation. It assumed that strains undergone by piezoelectric actuator, subject to an electric field generated dc bias voltage applied through couple lateral electrodes, are fully tra...

Abstract Magnetoelectric composites (x)PbZr 0.52 Ti 0.48 O 3 (PZT)-(1-x)NiFe 2 4 (NFO) with x values of 0.15, 0.30, 0.45, 0.55, 0.75, and 0.85 mol% were obtained by traditional solid phase reaction. The measured magnetic magnetostriction properties are strongly dependent upon the molar fraction (1-x) NFO in composites. maximum coefficient -52.4 ppm was observed 0.3PZT-0.7NFO composite ceramic. ...

Abstract The beneficial combination of micro- and nano-patterned surfaces with magneto-optical materials was investigated over the recent years. Due to their resonant behavior, these structures are commonly used enhance non-reciprocal effects. In this paper, a novel kind intensity effect is enhanced an all-dielectric grating patterned on magnetic nanocomposite layer. This latter formed by CoFe2...

The existence of a deformation and magnetization minimizing the magnetostrictive free energy is given. Mathematical challenges are presented by a free energy that includes elastic contributions defined in the reference configuration and magnetic contributions defined in the spatial frame. The one-to-one a.e. and orientation-preserving property of the deformation is demonstrated, and the satisfa...

In water splitting, the oxygen evolution reaction (OER) performance of transition metal alloy catalysts needs to be further improved. To solve this problem, method an external magnetic field was used improve OER catalytic catalyst. paper, FeCo alloys with different composition ratios were prepared by arc melting method, and compositions obtained annealing treatment. Under action a field, all th...

We present a methodology based on the N\'eel model to build classical spin-lattice Hamiltonian for cubic crystals capable of describing magnetic properties induced by spin-orbit coupling like magnetocrystalline anisotropy and anisotropic magnetostriction, as well exchange magnetostriction. Taking advantage analytical solutions model, we derive theoretical expressions parametrization integrals d...
