Micromagnetic simulations of ferromagnetic fine particle systems have been used to study the effect of various parameters on the hysteresis loops and on the ferromagnetic resonance (FMR) curves. Systematic calculations show that the effect of the dipolar interactions on such systems significantly differs from that introduced by the exchange interactions. It is important to note that the anisotropy and damping parameter also contribute to the FMR response. (C) 2001 American Institute of Physics.
