Abstract
The issues of designing bone implants capable of creating 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 (multiferroid) micro- and nanoparticles that are polarized under the action of an external magnetic field and create 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. Modeling the magnetoelectric effect in a composite particle is carried out; composite particles with cobalt ferrite as a magnetostrictor are fabricated, and the issues of the chemical interaction of phases are discussed.
