Giant Magnetoimpedance Sensors
Magnetoinductive e ects in ferromagnetic conductors can be used for various sensors. Although the principle has been known for a long time, the usefulness of these e ects for practical applications was recognized recently, and intensive investigations began. Magnetoinductive e ects are related to magnetization of a magnetic conductor (wire, strip, thin lm, etc.) by a magnetic eld, which is prod...
متن کاملHigh-temperature giant magnetoimpedance in Fe-based nanocrystalline alloy
Giant magnetoimpedance ~GMI! was investigated from room temperature up to 823 K in an Fe-based nanocrystalline Fe73.0Cu1.0Nb2.5V1.0Si13.5B9.0 ribbon. With an increment of the measuring temperature ~T!, GMI shows notable enhancement followed by a declining dependence, yielding a maximum value around 603 K where the relative GMI is nearly four times that at room temperature. The field at the peak...
متن کاملHIGH FREQUENCY MAGNETOIMPEDANCE OF FeNi/Cu/FeNi SENSITIVE ELEMENTS WITH DIFFERENT GEOMETRIES
In this work magnetoimpedance (MI) behaviour was studied experimentally for Fe19Ni81(175 nm)/Cu(350 nm)/Fe19Ni81(175 nm) sensitive elements deposited by rf-sputtering. A constant magnetic field was applied in plane of the sandwiches during deposition perpendicular to the Cu-lead in order to induce a magnetic anisotropy. Sandwiches with different width (w) of FeNi parts were obtained. The comple...
متن کاملGamma Irradiation Effect on Asymmetric Giant Magnetoimpedance of Co68.15Fe4.35Si12.5B15 Amorphous Alloy
The giant magneto impedance (GMI) effect is a large variation in the electrical impedance of a magnetic conductor when subjected to a static magnetic field. The sensitivity to the direction (AGMI) and magnitude of applied magnetic field and also linearity levels of this effect are three important parameters in magnetic sensors application. A suitable annealing procedure can be used to ac...
متن کاملEnhanced giant magnetoimpedance in heterogeneous nanobrush
A highly sensitive and large working range giant magnetoimpedance (GMI) effect is found in the novel nanostructure: nanobrush. The nanostructure is composed of a soft magnetic nanofilm and a nanowire array, respectively fabricated by RF magnetron sputtering and electrochemical deposition. The optimal GMI ratio of nanobrush is promoted to more than 250%, higher than the pure FeNi film and some s...
