Magnetic Field Sensors Techniques

Recent spatially resolved measurements of the electrostatic-potential variation across a Hall bar in strong magnetic fields, which revealed a clear correlation between current-carrying strips and incompressible strips expected near the edges of the Hall bar, cannot be understood on the basis of existing equilibrium th…

Bismuth nano-Hall sensors with dimensions ∼50 nm × 50 nm were fabricated using a combination of optical lithography and focused ion beam milling. The Hall coefficient, series resistance and optimum magnetic field sensitivity of the sensors were 4 × 10 -4 Ω/G, 9.1 kΩ and 0.8 G/√Hz, respectively. A 50 nm nano-Bi Hall se…

Abstract The advantages of planar Hall effect (PHE) sensors—their thermal stability, very low detection limits, and high sensitivities—have supported a wide range of advanced applications such as nano-Tesla (nT) magnetometers, current sensing, or low magnetic moment detection in lab-on-a-chip devices. In this review w…

A two-axis microelectromechanical systems micromirror actuator is developed for retinal scanning display and imaging applications. The device operation makes use of magnetostatic torque produced by the combination of a flux generating custom-made high-frequency electrocoil and the NiFe layer deposited on the movable p…

The main objective of this paper is to develop a linear actuator for an accurate position control with a high force-to-mass ratio. A novel configuration is developed that has a double-sided NdFeB stator and a printed-circuit moving armature. A design methodology is presented, which is based upon the finite-element met…

A system for detecting magnetic fields in the femtotesla range at low frequencies is developed, including the antenna, transformer, and amplifier. Each component is described with relevant tradeoffs which allow a large variety of receivers to be easily designed for any magnetic field sensing in the very low frequency…
