论文摘要
在这里，我们提出了一种磁性结构，用于使用不同波长的超短激光脉冲进行层选择性的磁化开关。它基于含有磁性GDFECO和非磁性介电层的chire磁晶体晶体（MPC）。在每个工作波长下，激光脉冲将加热到必要的水平，只有一个GDFECO层导致其磁化逆转，而不会对其他层的磁化产生任何影响。此外，讨论了MPC磁化状态的磁光读数。所考虑的MPC的横向尺寸可以使小足够小，以作为数据存储的单位单元格。
Here we propose a magnetophotonic structure for the layer-selective magnetization switching with ultrashort laser pulses of different wavelengths. It is based on a chirped magnetophotonic crystal (MPC) containing magnetic GdFeCo and nonmagnetic dielectric layers. At each operating wavelength the laser pulses heat up to necessary level only one GdFeCo layer that leads to its magnetization reversal without any impact on the magnetization of the other layers. Moreover, magneto-optical reading of the MPC magnetization state is discussed. Lateral dimensions of the considered MPC can be made small enough to operate as a unit cell for data storage.
