MAGNETIC SENSORS

Overview

The group activities cover up-stream research on physical phenomenon potentially useful for future sensors, as well as sensor development (proof of concept) and expertise to support industrial R&D. This experimental research is essentially based on magnetic (VSM, MOKE) and electric measurements (magnetotransport, noise).

Research topics

Magnetic sensor with tunable range

particles

Magnetic anisotropy can be controlled by electric field, which could lead to low-consumption devices. Our aim is to enhance the electric field effect by studying different materials. Eventually, this study will pave the way towards a magnetic field sensor with tunable range.

Ultra-sensitive magnetic field sensor

particles

We develop an ultra-sensitive magnetic field sensor able to detect 1pT at low frequency. This sensor could replace the magnetic sensors usually boarded on space mission with a significant weight reduction, or be used for magneto-cardiography.

Magnetic tunnel junctions for sensors

particles

To improve the quality of industrial magnetic field sensors, we develop sensitive and low-noise magnetic tunnel junctions, by addressing the influence of structure, materials and geometry.
