The fabrication and the study of the magnetic properties of CoCrPt/Ti nanostructures produced by sputtering onto ordered polymer templates are reported here. Samples exhibit a significant out-of-plane component of the magnetization higher than for planar films, and it is stronger for the thicker CoCrPt films, and for nanostructured films with the shorter period ordering. The shape of the polymeric templates plays an important role for the determination of magnetic easy-axis. Magnetic Force Microscopy images of the samples show a single magnetic domain structure with high out-of-plane anisotropy for the samples with longer ordering (480 nm period).
本文报道了通过溅射在有序聚合物模板上制备的CoCrPt/Ti纳米结构及其磁性能的研究。样品表现出比平面薄膜更高的面外磁化分量,对于较厚的CoCrPt薄膜以及周期排序较短的纳米结构薄膜,该分量更强。聚合物模板的形状在确定磁易轴方面起着重要作用。样品的磁力显微镜图像显示,对于具有较长排序(480 nm周期)的样品,呈现出具有高面外各向异性的单磁畴结构。
