Abstract
The dynamics of magnetization reversal of a nanocell composed of two magnetouniaxial nanoparticles by a short Gaussian magnetic-field pulse is investigated. This dipole-coupled system is multistable and has four equilibrium states. The conditions, under which the nanocell is switched to one of three states or returns to the initial configuration, are found. It is shown that the character of precession dynamics of the magnetic moment and choice of the final nanocell state depend on the pulse amplitude and width and the mutual easy-axis orientation.
