Fabrication of cobalt ferrite/piezoelectric composite particles for the use as magnetoelectric elements in bone implants
View through CrossRef
Bone implants capable to create an electrical stimulus for bone tissue regeneration under the influence of an external magnetic field are considered. A promising method for generating local electric fields is the use of magnetoelectric (multiferroic) micro- and nanoparticles, being polarized under the action of an external magnetic field, creating electric fields comparable in amplitude to endogenous ones. Of practical interest are composite magnetoelectric particles consisting of a ferrimagnetic core and a piezoelectric shell brought into close mechanical contact. The paper presents the results of modeling the magnetoelectric effect in a composite particle, fabrication of composite particles with cobalt ferrite as a magnetostrictive core, and considers the issues of the chemical interaction of phases.
