Submicrometer Hall devices fabricated by focused electron-beam-induced deposition

Radivoje Popovic, Giovanni Boero, Patrik Willi Hoffmann, Pavel Kejik, Niels Quack, Tristan Bret, Jürgen Brugger, Schahrazede-Lila Mouaziz

Hall devices having an active area of about (500 nm)(2) are fabricated by focused electron-beam-induced deposition. The deposited material consists of cobalt nanoparticles in a carbonaceous matrix. The realized devices have, at room temperature, a current ...

A novel planar magnetic sensor based on orthogonal fluxgate principle

Radivoje Popovic, Pavel Kejik, Franck Vincent, Ozge Zorlu

In this paper, we present a new planar fluxgate magnetometer structure. The sensor has the orthogonal fluxgate configuration which makes the detection part independent of the excitation mechanism. The sensor consists of a ferromagnetic cylindrical core cov ...

Low-power 2-D fully integrated CMOS fluxgate magnetometer

Radivoje Popovic, Pavel Kejik, Franck Vincent, Predrag Drljaca

In this paper, we present a low-power, two-axis fluxgate magnetometer. The planar sensor is integrated in a standard CMOS process, which provides metal layers for the coils and electronics for the signal extraction and processing. The ferromagnetic core is ...

First Fully CMOS-Integrated 3D Hall Probe

Radivoje Popovic, Pavel Kejik, Enrico Schurig

We present the first fully CMOS-integrated 3D Hall probe. The microsystem is developed for precise magnetic field measurements in the range from mT up to tens of tesla in the frequency range from DC to 30 kHz and with a spatial resolution of about 150 μm. ...

X-ray ferromagnetic resonance spectroscopy

Harald Brune, Radivoje Popovic, Giovanni Boero, Pietro Gambardella, Stefano Rusponi

We present a method to measure continuous-wave ferromagnetic resonance (FMR) spectra based on the core-level absorption of circularly polarized x rays. The technique is demonstrated by using a monochromatic x-ray beam incident on an yttrium-iron-garnet sam ...

CMOS imager based on single photon avalanche diodes

Pierre-André Besse, Radivoje Popovic, Alexis Rochas, Cristiano Niclass, Edoardo Charbon

In this paper we report on a 32×32 optical imager based on single photon avalanche diodes integrated in CMOS technology. The maximum measured dynamic range is 120dB and the minimum noise equivalent intensity is 1.3×-3lx. The minimum integration time per pi ...
