Abstract
Spatial resolution with a sharp permalloy rod on an HTS SQUID
microscope head was investigated. A 5 mm diameter and 10 mm long
permalloy rod with one side sharp and one side flat is placed In front
of a washer type SQUID with 0.1 mm spacing. A 0.3 mm line and space
meander line on a printed circuit board carrying current was used as a
magnetic field source. The SQUID microscope head with the sharp
permalloy rod scanned two dimensionally on the meander line inside the
magnetic shield. The 0.3 mm line and space meander line was resolved. We
also demonstrated imaging of laser-printed characters. This method has
the advantage of using a washer type SQUID with high magnetic
sensitivity, high spatial resolution and facilitating the adjustment of
the position and the measurement distance from the sample
