利用朗之万动力学模拟，我们计算了具有偶极粒子间相互作用的无序细磁性粒子系统的交流磁化率\(\chi = \chi' + i\chi''\)。我们已经表明，随着粒子浓度的增加，\(\chi''(T)\)峰的位移在定性上取决于单粒子各向异性，在定量上取决于进动阻尼。（C）2001爱思唯尔科学出版社。版权所有。
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.
