Response of Magnetic Nanoparticles Lattice to Gaussian Pulse of Magnetic Field

Resumo

Abstarct

The response of uniform and binary plane lattices of magnetic nanoparticles with uniaxial anisotropy to a short Gaussian pulse of magnetic field is studied in this work. It is shown that the dipole–dipole interaction and the presence of two types of nanoparticles modulate and decrease the response amplitude. The complicated periodic dependence of the amplitude and duration of the system response on the duration and peak value of the applied pulse has been discovered. The possibility of controlling the magnetization reversal of both the entire lattice and its parts by choosing the lattice composition and parameters of the bias field and pulse is demonstrated.
