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 while the sample exhibiting uniaxial anisotropy was made by reactive sintering using spark plasma sintering (SPS). This technique permits us to induce a magnetic anisotropy in cobalt ferrite in the direction of the applied pressure during the SPS process. Sample with uniaxial anisotropy revealed a… Expand
