Enhancement of the magnetoelectric effect in multiferroic CoFeO/PZT bilayer by induced uniaxial magnetic anisotropy
Alex Aubert, Vincent Loyau, Frédéric Mazaleyrat +1
In this study we have compared magnetic, magnetostrictive and piezomagnetic properties of isotropic and anisotropic cobalt ferrite pellets. The isotropic sample was prepared by the…
Uniaxial anisotropy and enhanced magnetostriction of CoFeO induced by reaction under uniaxial pressure with SPS
Alex Aubert, V. Loyau, F. Mazaleyrat +1
In this study, we have compared magnetic and magnetostrictive properties of polycrystalline CoFeO pellets, produced by three different methods, focusing on the use of Spark…
Analytical modeling of demagnetizing effect in magnetoelectric ferrite/PZT/ferrite trilayers taking into account a mechanical coupling
V. Loyau, A. Aubert, M. Lobue +1
In this paper, we investigate the demagnetizing effect in ferrite/PZT/ferrite magnetoelectric (ME) trilayer composites consisting of commercial PZT discs bonded by epoxy layers to…
A method to decrease the harmonic distortion in Mn-Zn ferrite/PZT and Ni-Zn ferrite/PZT layered composite rings exhibiting high magnetoelectric effects
V. Loyau, V. Morin, J. Fortineau +2
We have investigated the magnetoelectric (ME) effect in layered composite rings subjected to circumferential AC magnetic fields and DC magnetic fields in radial, axial or circumfer…
Direct calorimetric measurements of isothermal entropy change on single crystal W-type hexaferrites at the spin reorientation transition
Martino Lobue, Vincent Loyau, Frédéric Mazaleyrat +4
We report on the magnetic field induced isothermal entropy change, Δs(Ha, T), of W-type ferrite with CoZn substitution. Entropy measurements are performed by direct calorimetry. Si…
Analysis of volume distribution of power loss in ferrite cores
Martino Lobue, Vincent Loyau, Frédéric Mazaleyrat
We present a technique to estimate the inhomogeneities of magnetic loss across the section of ferrite cores under ac excitation. The technique is based on two distinct calorimetric…
