Abstract

We studied the magneto-optical and magnetic behavior of Co- and Fe-rich microwires that were stress-annealed at temperatures distributed along the microwire length. There was a transformation of the magnetic structure across zones subjected to annealing at different temperatures. Differences in the magnetic behavior between the surface and bulk were observed for both Co- and Fe-rich microwires. The formation and subsequent transformation of a helical magnetic structure were observed, depending on the type of microwire. Annealing at temperatures below 100 °C affected the magnetic system of microwires. This effect is due to a weak but noticeable relaxation of the initial stresses in all parts of the microwire that even occurs in the low temperature range.

梯度磁各向异性磁性微导线磁性能的纵向变换

我们研究了在沿微导线长度分布的温度下进行应力退火的富钴和富铁微导线的磁光和磁行为。在不同温度下进行退火的区域之间存在磁性结构的转变。对于富含Co和Fe的微丝，观察到表面和本体之间的磁性行为的差异。根据微导线的类型，观察到螺旋磁性结构的形成和随后的转变。在低于100°C的温度下退火会影响微导线的磁性系统。这种效应是由于微导线所有部分的初始应力的微弱但明显的松弛，甚至在低温范围内也会发生这种松弛。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
