Magnetic field detector, e.g. for rotational speed detection for internal combustion engine and braking control, has a giant magneto resistive element operating in a magnetic field of below eight-tenths of the saturation magnetic field

摘要

A magnetic field detector element (28) comprises a GMR element (7) operating in a magnetic field of below eight-tenths of its saturation magnetic field. Independent claims are also included for: (i) a process for producing the above magnetic field detector element; and (ii) a magnetic field detector comprising the above magnetic field detector element.
