Multiferroic BaTiO3-CoFe2O4 Nanostructures.
We report on the coupling between ferroelectric and magnetic order parameters in a nanostructured BaTiO3-CoFe2O4 ferroelectromagnet. This facilitates the interconversion of energies stored in electric and magnetic fields and plays an important role in many devices, including transducers, field sensors, etc. Such nanostructures were deposited on single-crystal SrTiO3 (001) substrates by pulsed l...
متن کاملNanolamellar magnetoelectric BaTiO3–CoFe2O4 bicrystal
Here, we report a spontaneously formed nanolamellar BaTiO3–CoFe2O4 bicrystal. 11̄0 interfaces join the BaTiO3 and CoFe2O4 single crystalline periodically arranged lamellae that have a common 111 direction. The superlattice of approximately 2 nm wavelength is magnetoelectric with a frequency dependent coupling coefficient of 20 mV/Oe cm at 100 Hz. The BaTiO3 component is a ferroelectric relaxor w...
متن کاملMagnetoelectric 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 کاملInfluence of Ga-concentration on the electrical and magnetic properties of magnetoelectric CoGaxFe2− xO4/BaTiO3 composite
Multiferroic materials exhibit magnetoelectric (ME) coupling and promise new device applications including magnetic sensors, generators, and filters. An effective method for developing ME materials with enhanced ME effect is achieved by the coupling through the interfacial strain between piezoelectric and magnetostrictive materials. In this study, the electrical and magnetic properties of Ga do...
