论文摘要
我们报告了同时在高压下同时执行宽大的氮胶囊（NV）钻石磁显微镜和同步加速器X射线衍射（XRD）测量。 NV颜色中心是在钻石砧座的库中创建的，该钻石砧座集成在钻石砧室中，用于静态压缩样品。 NV中心的光学检测到的自旋共振用于绘制样品磁化产生的杂散磁场。使用此组合方案，可以同时测量磁性和结构行为。作为原则证明，我们记录了铁的相关α-FE与铁的结构和磁过渡相关，在300 k时发生了15至20 GPa。
We report the possibility to simultaneously perform wide-field nitrogen-vacancy (NV) diamond magnetic microscopy and synchrotron X-ray diffraction (XRD) measurements at high pressure. NV color centers are created on the culet of a diamond anvil which is integrated in a diamond anvil cell for static compression of the sample. The optically detected spin resonance of the NV centers is used to map the stray magnetic field produced by the sample magnetization. Using this combined scheme, the magnetic and structural behaviors can be simultaneously measured. As a proof-of-principle, we record the correlated α-Fe to ε-Fe structural and magnetic transitions of iron that occur here between 15 and 20 GPa at 300 K.
