A scanning Hall probe microscope for high resolution, large area, variable height magnetic field imaging

We present a scanning Hall probemicroscope operating in ambient conditions. One of the unique features of thismicroscope 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 thex andy directions, with a scan resolution of 0.1 μm. Protocols have been implemented to enable scanning at different heights from the sample surface. Thez range is 35 mm. Microstructured Hall probes of size 1-5 μm have been developed. A minimum probe-sample distance
