摘要

收起

使用微波辅助聚合方法制备了单分散单畴Ni纳米球，由MFM发现，尺度分布在100~180 nm的Ni球的一个相关特征是条型磁畴结构。用XRD、TEM、XPS以及EDAX测量了由Ni球进一步制备的Ni_coreNiO_shell高度球型纳米结构。用VSM和SQUID进一步讨论了其铁磁/反铁磁界面耦合效应，估算了交换耦合场与粒子尺寸的关系。

Abstract

收起

Magnetic force microscopy (MFM) measurements were performed on monodispersed single-domain nickel nanospheres fabricated by the microwave-assisted (MW) polyol method. As found by MFM, a relevant characteristic of these spheres with a size distribution in the 100~180 nm range is the magnetic stripe domain structure. The obtained highly globular nanostructures of Ni_coreNiO_shell were measured by XRD, TEM, XPS, and EDAX. The ferromagnet/antiferromagnet interface coupling is discussed with the results of VSM and SQUID. The relation of the exchange-coupling field with particles sizes is evaluated.

Key words

monodispersed single-domain nickel nanospheres / Ni_coreNiO_shell / ferromagnet/antiferromagnet interface coupling
