Enhancement of the Magnetoelectric Effect in Multiferroic CoFe2O4/PZT Bilayer by Induced Uniaxial Magnetic Anisotropy

In this paper, we have compared magnetic, magnetostrictive, and piezomagnetic properties of isotropic and anisotropic cobalt ferrite pellets. The isotropic sample was prepared by the ceramic method…

Magnetic properties of bulk nanocrystalline cobalt ferrite obtained by high-pressure field assisted sintering

We present here an investigation aimed at exploring the role of the microstructure on the magnetic properties of nanostructured cobalt ferrite. Bulk, almost fully dense, nanograined ferrites have…

Tailoring the magnetic properties of cobalt ferrite nanoparticles using the polyol process

It is shown that the polyol solvent and the reaction time are two key parameters to control the size and the magnetic properties of the resulting nanoparticles, which are appropriate to be used as ferromagnetic building blocks in nanostructured magnetoelectric materials, particularly materials based on polymers.

Formation of pure s-phase in Mn–Al–C by fast annealing using spark plasma sintering

Mn–Al–C is intended to be one of the ‘‘gap magnets’’ with magnetic performance in-between ferrites and Nd-Fe-B. These magnets are based on the metastable ferromagnetic s-phase with L10 structure,…
