Planar Hall Effect Ring Sensors for High Field-Sensitivity

Abstract:

Article Preview

Planar Hall effect sensor has been explored using multi-layer cross-shaped and bridge geometry. We present planar Hall effect in a ring-shaped geometry experimentally that shows progress of sensor sensitivity as well as output signals. Sensitivity improves about 170 times compare to cross-shaped geometry and about 1.4 times to bridge geometry in conventional measurement system. These values become 2.5 times larger at 20o measurement system. The presented ring geometry may take great potential in Planar Hall effect sensor applications.
