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

Towards gate controlled devices

The control of magnetic interfacial properties by a gate voltage allows low power control of spintronic devices and provides a versatile, local and dynamic degree of freedom that can be implemented in innovative designs. Aiming at an efficient control of devices, we optimize materials and unravel the mechanisms of electric field effect on interfacial anisotropy, Dzyalonshinskii-Moriya interaction (DMI), and non-trivial spin textures such as skyrmions.

Ultra-sensitive sensor for space

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

Industrial sensor design

We provide design principles to the company Crocus Technology to target specific sensor performance in terms of sensitivity, noise, detectivity, linearity, and hysteresis. For this purpose, we perform electrical characterization, noise measurements and analysis, and numerical simulations.
