Abstract
A unit element of a magnetic device or a ferroelectric device and magnetic particles of a magnetic recording medium are provided. The outline of the unit element and the magnetic particles is arranged so as to have a portion topologically identical to one of a letter-C shape and a letter-S shape that correspond to the magnetization or polarization distribution immediately before the rotation of magnetization or polarization.
