Abstract

Systems of atoms or molecules can possess nonzero total spins that can be employed in spintronics, for instance for creating memory devices, which requires to be able to efficiently regulate spin directions. This article presents some methods of regulating spin dynamics, developed by the authors. These methods can be applied for different physical systems, described by different Hamiltonians including the interactions of spins with magnetic fields. The principal feature of the methods is the use of the feedback fields formed by moving spins.
