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 کاملMagnetoelectric coupling in the multiferroic compound LiCu2O2
We investigate the possible types of coupling between ferroelectricity and magnetism for the zigzag spin chain multiferroic compound LiCu2O2. We construct a multi-order-parameter phenomenological model for the material based on a group theoretical analysis. We find that a theory involving interchain magnetoelectric coupling belonging to the same unit cell explains the experimental results of Pa...
متن کاملSynthetic magnetoelectric coupling in a nanocomposite multiferroic
Given the paucity of single phase multiferroic materials (with large ferromagnetic moment), composite systems seem an attractive solution to realize magnetoelectric coupling between ferromagnetic and ferroelectric order parameters. Despite having antiferromagnetic order, BiFeO3 (BFO) has nevertheless been a key material due to excellent ferroelectric properties at room temperature. We studied a...
متن کاملDirect evidence for multiferroic magnetoelectric coupling in 0.9BiFeO3-0.1BaTiO3.
Magnetic, dielectric and calorimetric studies on 0.9BiFeO3-0.1BaTiO3 indicate strong magnetoelectric coupling. XRD studies reveal a very remarkable change in the rhombohedral distortion angle and a significant shift in the atomic positions at the magnetic Tc due to an isostructural phase transition. The calculated polarization using Rietveld refined atomic positions scales linearly with magneti...
متن کاملEffect of the Magnetostrictive Layer on Magnetoelectric Properties in Lead Zirconate Titanate/Terfenol-D Laminate Composites
Magnetoelectric laminate composites of piezoelectric/magnetostrictive materials were prepared by stacking and bonding together a PZT disk and two layers of Terfenol-D disks with different directions of magnetostriction. These composites were studied to investigate (i) dependence on the magnetostriction direction of the Terfenol-D disk and (ii) dependence on the direction of the applied ac magne...
