摘要： A system for suppressing low frequency magnetic noise from magnetoresistive sensors, the system including at least one magneto-resistive sensor including a free magnetic layer having a variable magnetisation, and a system for modifying magnetisation of the free magnetic layer, wherein the system for modifying magnetisation of the free layer is adapted to drive dynamics of the magnetisation of the free magnetic layer.
