Integrated semiconductor magnetic field sensors

Proceedings of the IEEE, 1986
A magnetic field sensor is an entrance transducer that converts a magnetic field into an electronic signal. Semiconductor magnetic field sensors exploit the galvanomagnetic effects due to the Lorentz force on charge carriers. Integrated semiconductor, notably silicon, magnetic field sensors, are manufactured using integrated circuit technologies ...

Advances in Magnetic Field Sensors

IEEE Sensors Journal, 2010
The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally found applications. We also review the development of miniaturization of fluxgate sensors and refer briefly to SQUIDs, resonant ...

Magnetic field sensor

The Physics Teacher, 2012
Earlier papers1–3 in this journal have described experiments on measuring the magnetic fields of current-carrying wires and permanent magnets using magnetic field probes of various kinds. This paper explains how to use an iPad and the free app MagnetMeter-3D Vector Magnetometer and Accelerometer4 (compass HD) to measure the magnetic fields.

Microstrip sensor of magnetic fields

2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004
Using a quasi-static approximation, the construction of a weak magnetic field sensor containing a thin magnetic film is researched and optimised. A sensitivity comparison of the sensor with a polycrystalline Permalloy film and the sensor with a monocrystalline yttrium-iron garnet film is carried out.

Integrated magnetic field sensor

Sensors and Actuators A: Physical, 1991
Abstract For small magnetic field measurements, Sextant Avionique is developing, in collaboration with the Ecole Superieure d'Ingenieurs en Electrotechnique et Electronique, a new generation of miniature sensors. The detector is a mechanical resonator using a monocrystalline silicon beam.

Graphene Magnetic Field Sensors

IEEE Transactions on Magnetics, 2010
Graphene extraordinary magnetoresistance (EMR) devices have been fabricated and characterized in varying magnetic fields at room temperature. The atomic thickness, high carrier mobility and high current carrying capabilities of graphene are ideally suited for the detection of nanoscale sized magnetic domains.

Magnetic field sensor by orthoferrites

Sensors and Actuators A: Physical, 1997
Abstract Among all ferromagnets orthoferrites possess the highest velocities of domain wall motion. Dynamic properties of a magnetic field meter based on domain wall dynamics in yttrium orthoferrite are reported. It is shown that at low driving magnetic fields and at frequencies up to the MHz band domain wall dynamics can be adequately described by ...

Active magnetic shielding with a magnetic field sensor

INTERMAG Asia 2005. Digests of the IEEE International Magnetics Conference, 2005., 2005
The shielding effect of a high-sensitivity magnetic field sensor and reverse excitation Helmholtz coil on the unidirectional noise magnetic field component was discussed in this paper. Results indicate that when the Helmholtz coil is small (about the same size as the sensor), a noise magnetic field of 60 Hz, 2.6 /spl times/ 10/sup -7/ T (p-p) can be ...

A magnetic field sensor and method of manufacturing a magnetic field sensor

1997
A method of manufacturing a magnetic field sensor having a stacked structure which comprises: a substrate (1); an exchange-biasing layer (2) comprising nickel oxide; a magnetic layer (3) which is exchange-biased with the exchange-biasing layer (2), whereby at least the exchange-biasing layer (2) is provided by sputter deposition using a sputter gas ...
