An integrating magnetic sensor based on the giant magneto-impedance effect

Enhanced giant magnetoimpedance in heterogeneous nanobrush

“…Since GMI changes as the function of external dc (direct current) magnetic field or applied dc/ac (alternating current) currents, it is possible to design GMI-based sensors that can measure either magnetic fields or dc/ac currents [2,3]. Based on the applied stress dependence of the GMI effect, new kinds of stress sensors have been proposed [4-6].…”

Co-based magnetic microwire and field-tunable multifunctional macro-composites

“…The outstanding soft magnetic properties resulting from amorphous structure and small size make them suitable for a wide application in magnetic sensors [6][7][8], especially their giant-magneto impedance (GMI) behavior has been of much research interest for many years [1,9,10]. GMI can be understood as a small variation of external magnetic field resulting in a large change of the high frequency impedance of a ferromagnetic wire and is related to a certain magnetic structure and soft magnetic properties of the wire.…”

Giant magnetoimpedance effect in NiFe/Cu plated wire with various plating thicknesses

“…A considerable interest has been focused on the giant magnetoimpedance (GMI) effect in the amorphous soft ferromagnetic materials because of their important applications in highly sensitive micromagnetic sensors [1][2][3]. The GMI effect can be defined as the change of the impedance of a soft magnetic element carrying a high frequency current as a function of the external dc magnetic field, H.…”
