NanoSQUID as magnetic sensor for magnetic nanoparticles characterization
Journal of Nanoparticle Research, 2011Integrated magnetic sensors based on niobium dc SQUID (Superconducting Quantum Interference Device) for nanoparticle characterizations are presented. The SQUIDs consists of two Dayem bridges of 90 nm × 250 nm and loop area of 4, 1, and 0.55 μm2. The devices are realized by using an e-beam lithography nano-fabrication process which can directly pattern ...

Proceedings of the IEEE, 1990
Eleven of the most common technologies used for magnetic field sensing are described and compared. These are the search coil, flux-gate, optically pumped, nuclear precession, SQUID, Hall-effect, magnetoresistive, magnetodiode, magnetotransistor, fiber optic, and magnetooptic technologies.

On the modelling of a CMOS magnetic sensor
1994 IEEE International Symposium on Circuits and Systems (ISCAS), 1994Magnetic sensors are useful in applications such as magnetic read heads and non-contact current sensors. Ideally, a magnetic sensor should be easily integrated with its peripheral circuits. Experimental results indicate that it is possible to convert a conventional MOS transistor into a magnetic sensor by splitting the drain of the device into two ...

Sensors Based on Magnetic Fluids
2013Magnetic fluids are materials that can be successful used in sensors and actuators as the active mass. Due to their intrinsic nature, magnetic fluids can be manipulated and controlled by suitable magnetic field which can modify their physical properties such as density and viscosity.

In this chapter, we describe the use of individual nitrogen–vacancy (NV) centers in diamond as nanoscale sensors for magnetic- fi eld detection and imaging. We start by reviewing the original proposals and fi rst proof- of-concept experiments for NV magnetometry and then discuss recent applications of this emerging technology.

IEEE Transactions on Geoscience Electronics, 1965
In magnetic surveys it is often more useful to deal with the magnetic field gradients than with the field itself. This paper describes a device which measures magnetic field gradients directly and which is not influenced by uniform magnetic fields. Even if asymmetries exist in the device, the constant part of the magnetic field will appear as a signal ...
