摘要：
由于纳米粒子在药物输送、磁流体力学、磁数据存储、传感器、磁共振成像、肿瘤治疗等方面的潜在应用，纳米粒子系统正处于理论和实验研究的前沿。最近，据报道，相互作用的纳米粒子表现为自旋玻璃，并且实验表明这些系统的弛豫服从拉伸指数，即，KWW放松。因此，在这项研究中，考虑到相互作用的纳米粒子系统，我们模拟的弛豫和调查频率和温度行为取决于缓慢的弛豫，通过使用一个简单的运营商形式主义。我们表明，弛豫偏离德拜和服从KWW的记忆效应的存在下，在系统中。此外，我们得到的频率和温度行为依赖于KWW弛豫。我们得出的结论是，所得到的结果与实验结果和简单的模型，这里提出的，是非常有用的和教学讨论的相互作用的纳米粒子的慢松弛。
英文摘要：
The nano-particle systems under theoretically and experimentally investigation because of the potential applications in the nano-technology such as drug delivery, ferrofluids mechanics, magnetic data storage, sensors, magnetic resonance imaging, and cancer therapy. Recently, it is reported that interacting nano-particles behave as spin-glasses and experimentally show that the relaxation of these systems obeys stretched exponential i.e., KWW relaxation. Therefore, in this study, considering the interacting nano-particle systems we model the relaxation and investigate frequency and temperature behaviour depends on slow relaxation by using a simple operator formalism. We show that relaxation deviates from Debye and obeys to KWW in the presence of the memory effects in the system. Furthermore, we obtain the frequency and temperature behaviour depend on KWW relaxation. We conclude that the obtained results are consistent with experimental results and the simple model, presented here, is very useful and pedagogical to discuss the slow relaxation of the interacting nano-particles.
