Abstract The Monte Carlo simulation of the critical behavior of multilayer structures based on anisotropic Heisenberg model is performed. The analysis reveals aging effects characterized by a slowing down of the relaxation and correlation characteristics in the system with the waiting time. The dependence of aging characteristics on thickness of ferromagnetic films is investigated. The investigation of non-equilibrium critical behavior of multilayer structure which correspond to the nanoscale superlattice Co/Cu/Co demonstrates that the aging effects can be observed in a wider temperature range than for bulk magnetic systems.

多层磁结构的非平衡临界动力学

摘要 对基于各向异性海森堡模型的多层结构临界行为进行了蒙特卡罗模拟。该分析揭示了老化效应，其特征是系统中的松弛和相关特性随着等待时间的延长而减慢。研究了老化特性对铁磁薄膜厚度的依赖性。对对应于纳米级超晶格 Co/Cu/Co 的多层结构的非平衡临界行为的研究表明，与体磁系统相比，可以在更宽的温度范围内观察到老化效应。
