Crossfield Sensitivity in AMR Sensors
(IEEE, 2009-10)
We discuss the origin of the crossfield sensitivity of AMR sensors, the way how this error may influence the performance of an AMR compass and methods for its correction. Finally, we confirm the simple formulas experimentally. ...
AMR Gradiometer for Mine Detection
(Elsevier Science, 2012)
Anisotropic magnetoresistors (AMRs) are used to build an advanced mine detector. The sensing head involves a gradiometric pair of AMR sensors and a continuous-wave driven excitation coil, so the gradiometer is capable of ...
