|Full description: |
In order to characterize the magnetic properties of materials such as steels or nanoparticles, an ultra-sensitive and quantitative magnetic microscope is being developed at the Nanomagnetism and Oxides Laboratory. This microscope combines a local scanning probe microscope of the AFM type (Atomic Force Microscope) and a magnetic sensor integrated in an AFM flexible cantilever. The magnetic sensors used are giant magnetoresistance sensors, based on spin electronics and capable of detecting magnetic fields in the order of nT/√Hz.
The aim of the internship will be to study the performance of the sensors in terms of magnetoresistance and noise when integrated into the flexible cantilever. The response of the sensors should be optimized according to the application. The internship will therefore have a microfabrication aspect in a clean room and a transport and noise measurement aspect, which will be carried out in the shielded room of the Ultra Low Noise platform.
The developed probes will then be integrated into the microscope to produce magnetic images.
