摘要：
A magnetometer includes a magnetoresistive element and first and second high-permeable laminated flux collectors of height H partially overlapping, respectively, opposing lateral edges of the magnetoresistive element, wherein the flux collectors are separated laterally by a gap of length G which the magnetoresistive element spans. The two laminated flux collector and the magnetoresistive element cooperatively form an open-loop flux-conducting path of total height 2H+G, that is capable of collecting flux of a magnetic field being measured and, in response to the flux collected, developing a magnetometive force across the gap G that is functionally related to the height of the flux collectors.
