Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...
Information about the poloidal field inside the plasma and about the current density profile is essential for the understanding of the behavior of tokamak plasmas. The poloidal field outside the plasma edge is easily measured by a set of magnetic coils, wh ...
We present an open-loop CMOS current transducer without magnetic core consisting of a bus bar and a CMOS integrated magnetic sensor. The magnetic sensor is a combination of a circular vertical Hall device for low-frequency range and a pick-up coil for high ...

The aim of this thesis is to get a deeper understanding of magnetic properties of small clusters when they are embedded in a host material. The study was motivated by the observation of the very peculiar properties that clusters present in the gas phase or ...
We present a technique for contactless angular position sensing that allows low power consumption while keeping dynamic properties comparable to existing sensors. The technique essentially consists in combining a recently developed sensing element, the so- ...

A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises two sensing structures (1A 1B) that can be operated as a rotating Hall element. The two Hall elements are rotated in discrete steps in opposite directions. Such a ma ...
In order to sort out the physics that is important in many plasma experiments, data in three dimensions 3D are becoming necessary. Access to the usual cylindrical vacuum vessel is typically restricted to radially or axially insertable probes that can pivot ...
One of the most hindering limitations in the simulation of a realistic biological system is the complexity of the model which may easily lead to a very heavy computational burden. This may seriously question the possibility of optimizing system parameters ...

We observed the second harmonic voltage response of pseudo-spin valves subjected to currents oscillating at frequencies in the sub-kilohertz range. Peaks appear in its magnetic field dependence, with a signal-to-noise ratio equal to or greater than the mag ...
We developed a new integrated magnetic sensor based on the Hall effect, suitable for contactless 360 degrees absolute angle encoding. The sensing device consists of a narrow n-well ring with a chain of 64 contacts equally distributed along the ring. It is ...
