标题： A Scanning Hall Probe Microscope for high resolution, large area, variable height Magnetic Field Imaging

摘要： 我们介绍一种在环境条件下运行的扫描霍尔探针显微镜。 该显微镜的一个独特功能是同时使用相同的步进电机进行样品定位和扫描，这使得在x和y方向上可以实现几毫米的扫描范围，扫描分辨率为0.1 $\mu$m。已经实现了用于在不同高度扫描的协议。 z方向的范围是35 mm。 已经开发了尺寸为1-5 $\mu$m的微结构霍尔探针。 通过结合新型霍尔探针和基于音叉的力检测技术的探针-样品距离调节，获得了最小的探针-样品距离 \textless{} 2 $\mu$m。 该系统还可以记录局部 B(z) 曲线。 我们讨论了该显微镜在研究为微系统应用而开发的微磁阵列中的应用。 * gorky.shaw@ulg.ac.be. ; 现地址： 显示英文摘要

摘要： We present a Scanning Hall Probe Microscope operating in ambient conditions. One of the unique features of this microscope is the use of the same stepper motors for both sample positioning as well as scanning, which makes it possible to have a large scan range (few mm) in x and y directions, with a scan resolution of 0.1 $\mu$m. Protocols have been implemented to enable scanning at different heights from the sample surface. The z range is 35 mm. Microstructured Hall probes of size 1-5 $\mu$m have been developed. A minimum probe-sample distance \textless{} 2 $\mu$m has been obtained by the combination of new Hall probes and probe-sample distance regulation using a tuning fork based force detection technique. The system is also capable of recording local B(z) profiles. We discuss the application of the microscope for the study of micro-magnet arrays being developed for applications in micro-systems. * gorky.shaw@ulg.ac.be.; Present address:
