摘要:

本文报道了纯铬中磁位错的研究。相干X射线衍射曲线上获得的无公度自旋密度波(SDW)反射是一致的存在下的位错的磁秩序,嵌入在几个微米的样品的表面。除了铬中磁位错的具体情况外,这项工作可能为研究嵌入体中的磁缺陷开辟了一种新方法。

英文摘要:

We report on the study of a magnetic dislocation in pure chromium. Coherent x-ray diffraction profiles obtained on the incommensurate Spin Density Wave (SDW) reflection are consistent with the presence of a dislocation of the magnetic order, embedded at a few micrometers from the surface of the sample. Beyond the specific case of magnetic dislocations in chromium, this work may open up a new method for the study of magnetic defects embedded in the bulk.
