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).
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.

- GREAT – A H2020 ICT project at SPINTEC (June 30th, 2016)
Overview GREAT (European H2020 project) was accepted at the Summer 2015. Its kick-off meeting took place at SPINTEC in Grenoble on February 22nd-23rd 2016. The project aims at developing magnetic stacks able to equally perform memory, radio-frequency ...
- Magnetic sensors (September 11th, 2015)
Thematic overview Spintec was originally heavily involved in read heads for disk drive, yet this activity all but vanished due to the strong consolidation of the industry, now with only two players with strong internal R&D ...
- Integrated monolithic 3D magnetic compass (September 02nd, 2015)
Integrated monolithic 3D magnetic compass G. Gaudin, Ph. Sabon, C. Baraduc, A. Schuhl, I.L. Prejbeanu We developed a new 3D magnetometer concept, fully integrated, more compact, more accurate and more efficient than current solutions. This magnetometer is ...
