Abstract |
The thermally activated magnetic relaxation in two-dimensional lattices of dipolar interacting nanoparticles with large uniaxial perpendicular anisotropy is studied by a numerical method and
within the mean-field approximation for comparison. The role that the correlation effects play in
magnetic relaxation and the influence of lattice structure and bias magnetic field on the relaxation
process are revealed. The correlations of the nanoparticle magnetic moments enhance relaxation on
small times, delay it on large times, and reduce the steady-state absolute magnetization at nonzero
bias fields. In a hexagonal lattice, magnetic relaxation on small times occurs faster and the
steady-state absolute magnetization has the larger magnitude than in a square lattice with the same
lattice spacing.
