Bi-Directional Giant Magneto Impedance Sensor
A thin film giant magneto impedance (GMI) based on magnetic field sensor has been developed using electrodeposited Ni-Fe permalloy. Chemical composition, surface morphology, and magnetic properties of Ni-Fe permalloy were characterized as a function of plateup parameters, and process conditions were established to deposit a Ni-Fe thin film with a high permeability (~1000) and a low coercivity (...
متن کاملEffect of annealing on torsion giant impedance of Co-rich amorphous wires with vanishing magnetostriction
Torsion giant impedance ~TGI! ratio, (DZ/Z)j , has been measured in as-cast and annealed ~Co0.94Fe0.06)72.5B15Si12.5 amorphous wire. Two-step current annealing has been employed: pre-annealing ~550 mA, 2 min! plus current annealing under torsion stress ~33 p rad/m, 450 mA, up to tann5105 min!. Pre-annealing results in a drastic increase of (DZ/Z)j ~from 155% to 260%! and decrease of the asymmet...
متن کاملExchange biasing in ferromagnetic amorphous wires: A controllable micromagnetic configuration
Nonmagnetostrictive Co-rich amorphous wires, 130 mm in diameter, were stress annealed to induce a transverse anisotropy. The resultant structure consists of a circular-magnetization single domain except in a thin core, 2 mm in diameter, where magnetization is axially oriented. The wall interconnecting the outer shell with the core magnetization induces a local helical anisotropy during the anne...

Operating Point Self-Regulator for Giant Magneto-Impedance Magnetic Sensor
The giant magneto-impedance (GMI) magnetic sensor based on the amorphous wire has been believed to be tiny dimensions, high sensitivity, quick response, and small power consumption. This kind of sensor is usually working under a bias magnetic field that is called the sensor's operating point. However, the changes in direction and intensity of the external magnetic field, or the changes in sensi...
