The magnetic moment response of a magneto-uniaxial nanoparticle and a flat lattice of similar nanoparticles are being studied under the action of a short Gaussian pulse of a magnetic field in the presence and in the absence of its modulation. The periodic dependence of the final orientation and duration of a response of the magnetic moments on the pulse duration and its peak value have been revealed and analyzed. The effect on processes magnetization reversal of a weak magnetizing field and the deviation of the pulse of field from the transverse orientation has been studied. Have been shown that the influence of the dipole-dipole interaction leads to modulation of the response to the pulse action.
