AI中文摘要:
低温下的宽场氮空位(NV)磁成像需要微波激励以及传感区域附近温度的可靠信息。本文报告了一种集成金刚石量子传感平台,该平台在同一金刚石衬底上结合了NV中心集合与掺硼金刚石(BDD)微波天线和温度计。BDD天线为光学检测磁共振测量提供微波激励,BDD温度计则监测NV传感区域附近的热环境。BDD温度计检测到了载物台安装的温度计未清晰分辨的激光诱导局部加热。利用该平台,我们在记录温度的同时对多个铜酸盐超导体的温度相关迈斯纳响应进行了成像。这些结果表明,集成BDD-NV平台为低温宽场磁成像提供了一种实用方法,兼具集成微波传输与局部测温功能。
英文摘要:
Wide-field nitrogen-vacancy (NV) magnetic imaging at cryogenic temperatures requires microwave excitation and reliable knowledge of the temperature near the sensing region. Here, we report an integrated diamond quantum-sensing platform combining an ensemble of NV centers with a boron-doped diamond (BDD) microwave antenna and thermometer formed on the same diamond substrate. The BDD antenna provides microwave excitation for optically detected magnetic resonance measurements, and the BDD thermometer monitors the thermal environment near the NV sensing region. The BDD thermometer detected laser-induced local heating that was not clearly resolved by a stage-mounted thermometer. Using this platform, we imaged the temperature-dependent Meissner response of multiple cuprate superconductors while recording the temperature. These results demonstrate that the integrated BDD--NV platform provides a practical approach for cryogenic wide-field magnetic imaging with integrated microwave delivery and local thermometry.
