Fast magnetization reversal of nanoclusters in resonator
摘要：
提出了一种实现纳米团簇超快磁化反转的有效方法。该方法基于将纳米团簇耦合到谐振电路。这种耦合导致作用于团簇的磁反馈场的出现，这大大缩短了磁化反转时间。分析了谐振器特性、纳米团簇参数和外场对磁化动力学和反转时间的影响。磁化反转时间可以比自然弛豫时间短许多数量级。反转研究的情况下，一个单一的纳米团簇，以及为系统的许多纳米团簇相互作用，通过偶极力。
英文摘要：
An effective method for ultrafast magnetization reversal of nanoclusters is suggested. The method is based on coupling a nanocluster to a resonant electric circuit. This coupling causes the appearance of a magnetic feedback field acting on the cluster, which drastically shortens the magnetization reversal time. The influence of the resonator properties, nanocluster parameters, and external fields on the magnetization dynamics and reversal time is analyzed. The magnetization reversal time can be made many orders shorter than the natural relaxation time. The reversal is studied for both the cases of a single nanocluster as well as for the system of many nanoclusters interacting through dipole forces.
