论文摘要
这项工作提出了一种基于钻石晶体中的颜色中心的磁场成像方法，该钻石晶体应用于纳米胶质的Mn $ _2 $ GAC最大相位的薄膜。通过在200 K和235 K之间进行测量，表面特征在214 K处的一阶转变围绕一阶转变围绕表面相关结构的磁性特性，而表面特征通过将温度提高到过渡温度以上而逐渐消失。此处介绍的结果表明，基于氮的磁显微镜如何补充传统使用的一组实验技术，提供了显微镜尺度磁场特征的其他信息，并允许研究依赖温度的磁性行为。以这种方式获取的附加信息与表面磁性本质上的应用有关。
This work presents a magnetic field imaging method based on color centers in diamond crystal applied to a thin film of a nanolaminated Mn$_2$GaC MAX phase. Magnetic properties of the surface related structures have been described around the first order transition at 214 K by performing measurements in the temperature range between 200 K and 235 K with the surface features fading out by increasing temperature above the transition temperature. The results presented here demonstrate how Nitrogen-Vacancy center based magnetic microscopy can supplement the traditionally used set of experimental techniques, giving additional information of microscopic scale magnetic field features, and allowing to investigate the temperature dependent magnetic behavior. The additional information acquired in this way is relevant to applications where surface magnetic properties are of essence.
