Magnetic nanostructures revealing exchange bias effect have gained a lot of interest in recent years due to their possible applications in modern devices with various functionalities. In this paper, we present our studies on patterned [CoO/Co/Pd]₁₀ multilayer where ferromagnetic material is in a form of clusters, instead of being a continuous layer. The system was patterned using nanosphere lithography technique which resulted in creation of an assembly of well-ordered antidots or islands over a large substrate area. We found that the overall hysteresis loop of the films consists of hard and soft components. The hard component hysteresis loop exhibits a large exchange bias field up to −11 kOe. The patterning process causes a slight increase of the exchange field as the antidot radius rises. We also found that the material on edges of the structures gives rise to a soft unbiased magnetization component.

[CoO / Co / Pd] ₁₀ Antidot大面积阵列中的交换偏差

近年来，具有交换偏置作用的磁性纳米结构因其在具有各种功能的现代设备中的应用而备受关注。在本文中，我们介绍了关于图案化[CoO / Co / Pd] _10的研究铁磁性材料呈簇状而不是连续层的多层。使用纳米球体光刻技术对该系统进行了图案化，从而在较大的基板面积上形成了排列整齐的解毒剂或岛状物。我们发现，薄膜的整体磁滞回线由硬组分和软组分组成。硬组分磁滞回线显示出高达-11 kOe的大交换偏置场。随着解毒点半径的增加，构图过程会引起交换场的轻微增加。我们还发现，结构边缘上的材料产生了柔软的无偏磁化分量。
