Micromagnetic Simulation of the Magnetoelastic Effect in Submicron Structures

Аннотация

The effect of deformations on magnetic nanoparticles of elliptic, square, and triangular shapes is simulated. The distribution of the magnetization of such particles is studied as functions of their shapes and applied deformations. A deformation is shown to possibly lead to the formation of new metastable states and also a change in the type of the ground state of a particle. The deformation substantially changes the distribution of the particle magnetization, which can be detected by their MFM contrast.
