摘要：

Using Langevin dynamics simulations, we have calculated the AC-suseeptibility chi = chi' + i chi " of disordered fine magnetic particle systems with the dipolar interparticle interaction. We have shown that the shift of the chi " (T)-peak with increasing particle concentration depends qualitatively on the single-particle anisotropy and quantitatively on the precession damping.
