Description of the offer :

The overall strategy of the LNO at SPEC is in-depth understanding of magnetism in condensed matter with a good balance between state-of-the-art research, development of new instruments, and applications. This equilibrium is possible in this field where applications and research are very close. The LNO has specific skills, tools and expertise on the characterization and the development of magnetoresistive sensors with very high sensitivity and for various applications as magnetophysiology, MRI (Magnetic Resonance Imaging), nanometrology, NDT (Non Destructive Testing), automotive...

The postdoc will work in the frame of the ANR (Agence Nationale pour la Recherche) JCJC project CARAMEL. The aim of the project is to develop a novel characterization tool of the magnetic properties of the material surface with an expected submicron resolution by combining very sensitive magnetoresistive (MR) sensors and atomic force microscopy. This microscope could have possible applications and impact in various domains from fundamental to industrial. New perspectives for material characterization and analysis will be opened, for example in situ following, non-destructive testing and nanometrology.

The postdoc will work on the development of the microscope and the addition of two functionalities: magnetic nanometrology and magnetic susceptibility imaging. He/she will show the proof of concept on calibration samples. The postdoc will also participate to the development of GMR and TMR sensors adapted to the application.
