扫描霍尔探针显微镜（SHPM）是一种基于霍尔效应纳米传感器的新型磁成像技术，在纳米级超导和铁磁材料的定量绘图方面具有重要应用。它与其他成像方法（例如磁力显微镜（MFM））高度互补。 SHPM 几乎完全是非侵入性的，可在较宽的温度 (0.3–300 K) 和磁场 (0–7 T) 范围内使用，并且在需要具有非常高的信噪比的磁感应定量图时特别有价值。将通过相关成像案例研究来描述和说明传感器技术的最新发展。此外，还将回顾纳米级霍尔传感器在微磁力测量中的应用。
Scanning Hall probe microscopy (SHPM) is a novel magnetic imaging technique based on Hall-effect nanosensors with important applications in the quantitative mapping of nanoscale superconducting and ferromagnetic materials. It is highly complementary to other imaging approaches, e.g., Magnetic Force Microscopy (MFM). SHPM is almost completely non-invasive, can be used over a wide range of temperatures (0.3–300 K) and magnetic fields (0–7 T) and is particularly valuable when quantitative maps of magnetic induction are required with very high signal:noise ratios. Recent developments in sensor technology will be described and illustrated by relevant imaging case studies. In addition applications of nanoscale Hall sensors in micro-magnetometry will be reviewed.
