Description of the thesis topic
The project objectives are: to engineer thin magnetic films hosting chiral domain walls and skyrmions; to tune and control the static and magnetic properties of domain walls and skyrmion with an electric field; to model the skyrmion stability as a function of morphology and magnetic properties.
The student will carry out an experimental and theoretical work. He/she will prepare thin magnetic layers by magnetron sputtering; will characterize the magnetic properties and will observe magnetic textures with magnetic microscopy techniques (Kerr, AFM-MFM); will pattern the thin films using electron beam microscopy in cleanroom environment; will study static and magnetic properties of skyrmions and domain walls under spin polarized current and electric field; will use theoretical models to evaluate the stability of skyrmions as a function of the magnetic properties of the material.
This project will take place at the Institut Néel, one of the largest French laboratories dedicated to applied physics. The candidate will be hosted by the Micro and Nanomagnetism team. This international team (25 people) studies and develops thin films of magnetic materials and their applications to spintronics, biology and energy. The research project is funded by the the EU's Marie Sklodowska Curie Innovative Training Network MagnEFi - Magnetism and the Effects of Electric Field, comprising 11 industrial and academic partners.
Constraints and risks
Experiments in synchrotron radiation centers outside France may be envisaged. The European project imposes several weeks secondments in selected partner laboratories.
