Summary

The aim of the internship is to develop and test a compact magnetometer enabling field measurement in all three directions. The magnetometer will use the principles of spin electronics and can be used for precision magnetometry (nanotelsa).

Full description

This project is part of the PEPR SPIN ADAGE project, which aims to develop more sensitive, adaptable and agile magnetic field sensors.

The problem here is the integration of spin electronics and magnetic textures to create compact devices, potentially on a single chip, for measuring magnetic fields in all three directions.
The internship will involve studying the underlying physics of magnetoresistive stacks, and then using microfabrication technologies to fabricate complete devices, combined with discrete electronics.

The magnetometers will then be qualified in terms of performance (sensitivity, range, noise, detection limit) on SPEC’s Ultra-Low Magnetic Noise platform.

They will then be destined for applications such as space or neural signal measurement.
