摘要
我们报道了通过化学镀制造的具有极长纵横比的铁磁CoNiB纳米管中磁畴的成像。虽然对于由软磁材料制成的长管预期为轴向磁化，但我们证实了系列方位角畴的存在。我们尝试通过各向异性应变和/或晶粒尺寸与磁弹性和/或各向异性界面磁各向异性的相互作用来解释这些现象。该材料可能对高密度数据存储以及曲率诱导的磁现象（如自旋波传播的非互易性）有意义。

备注
Focus only on azimuthal domains, information on domain walls (part of v1) removed - title, abstract and discussion changed accordingly, tubular racetracks scheme removed; new references, figures. Submission to SciPost (reformatted, new abstract, DOI added to references). Enhanced discussion of anisotropy, disagreement of synchrotron data and magnetometry rectified, new MOKE data added
