Abstract

The field-driven magnetization reversal in a three-dimensional network of ferromagnetic particles of ellipsoidal shape is analytically studied with an emphasis on coupling among the particles. The considered governing dynamics is the Landau–Lifshitz equation of micromagnetism which delineates the motion of magnetization inside the ferromagnetic medium. The analytical results explicate the stability and controllability (reversal) of the relevant configurations of magnetization which are established under the sufficient conditions. To reverse the magnetization direction in the particles, we use the control as a magnetic field generated by a dipole whose position and strength can be chosen.
