The magnetic field range in which a magnetic sensor operates is an important consideration for many applications. Elliptical planar Hall effect (EPHE) sensors exhibit outstanding equivalent magnetic noise (EMN) on the order of pT/Hz, which makes them

We report a specially designed magnetic field gradiometer based on a single elliptical planar Hall effect (PHE) sensor, which allows measuring magnetic field at nine different positions in a 4 mm length scale. The gradiometer detects magnetic field g

We introduce a planar Hall effect magnetometer in the form of a parallel array of permalloy-based elliptical sensors. The number of ellipses in the array and other fabrication parameters are optimized with the support of numerical simulations. We obt

Using planar Hall effect sensors with magnetic flux concentrators, we measure magnetic fields at frequencies below 100 Hz. We show that for a measurement time of up to 100 s, it is possible to detect fields of ∼700 fT and ∼1 pT at 10 Hz and 0.1 H

We integrate elliptical planar Hall effect (PHE) magnetometers with optimized high permeability magnetic flux concentrators. The integrated magnetometers exhibit at room temperature an equivalent magnetic noise of ∼5 pT/√Hz at 10 Hz, 7.4 pT/√Hz

Recent reports have demonstrated field resolutions of planar Hall effect magnetometers in the picotesla range. Here, we report a significant improvement in the field resolution of these sensors by decreasing their preamplifier white noise and the sen

We fabricate elliptical planar Hall effect magnetometers with Permalloy thickness ranging between 25 and 200 nm. We study the thickness dependence of their equivalent magnetic noise by examining the effect of the layer thickness on the signal and noi

A method for the compensation of crosstalk in three-axial induction magnetometers is developed theoretically and verified experimentally. The compensation is based on deriving crosstalk-free magnetometer outputs from a system of equations describing
