Equilibrium Distribution of Magnetization and Processes of Magnetization Reversal in Magnetoelastic Nanostructures

摘要

Results are presented from an experimental study of the equilibrium distribution of magnetization and processes of magnetization reversal of magnetoelastic nanostructures in the form of strips with constant or variable width. It is shown that the symmetry of the stable magnetization states in the nanostrip can be broken by a static magnetic field applied perpendicular to the ferromagnet’s easy axis. A further change in the states of magnetization allows their manipulation (e.g., moving the domain wall) using the homogeneous mechanical effects induced by applying an electric field to the piezoelectric substrate.
