Anisotropic Magnetoresistor Cross Axis Effect Measurement

Original language description

Anizotropic magnetoresistive (AMR) sensors show unwanted sensitivity to the external field applied in the direction perpendicular to their axis of sensitivity. This cross axis effect can cause an error of the magnetic field amplitude reading when the applied field is not parallel to the direction of the axis of sensitivity. This paper presents a simple method, how to measure the cross axis effect and also results of the Honeywell HMC 1002 sensor measurement. The theory of AMR sensors is discussed in [1]. The AMRs are presently being used for sensing small fields such as the Earth's field (~ 48 uT amplitude, ~ 18 uT horizontal component - central Europe) for navigation purposes. Elimination of all possible sources of errors such as cross axis effect error is then necessary for accurate measurement and direction determining.
