Magnetic particle embedded in a piezoelectric matrix: analysis and applications
Résumé
We take into consideration a nonlinear magnetostrictive particle embedded in a piezoelectric matrix in order to obtain (stress mediated) magneto-electric effects with applications to memory cells. The micromechanical analysis is conducted through the magneto-electro-elastic Eshelby tensor in an anisotropic environment. The results show the equilibrium orientations of magnetization versus the applied fields and the boundary conditions. In particular, a bi-stable behaviour (controlled by the applied electric field) can be obtained and it could be useful for applications to memory cells design.
