CMOS magnetic-field sensor system
IEEE Journal of Solid-State Circuits, 1994A magnetic-field sensor system integrated in CMOS technology with additional processing steps necessary for sensor fabrication is presented. The system contains a magnetoresistive permalloy microbridge acting as a sensor, temperature compensation circuitry, programmable readout electronics, reference voltage bias, and clock generation.

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.

Magnetoelectric Sensor of Magnetic Field
Ferroelectrics, 2002As an alternative to semiconductor sensor and sensor on hermetic contacts we present sensor based on magnetoelectric effect. In researches there are used the magnetoelectric bulk composites containing 95% of yttrium-iron garnet and 5% of lead zirconate titanate (PZT) and multilayer composite material consisting of PZT and Ni 0.5 Zn 0.5 Fe 2 O 4 .

Journal of Applied Physics, 2010
We present a theoretical study of the spatially averaged in-plane magnetic field on square and rectangular magnetic field sensors from a single magnetic bead, a monolayer of magnetic beads, and a half-space filled with magnetic beads being magnetized by the magnetic self-field due to the applied bias current through the sensor.

Microstrip sensor of magnetic fields
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004Using 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.

Graphene Magnetic Field Sensors
IEEE Transactions on Magnetics, 2010Graphene 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, 1997Abstract 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 ...
