Préparation et études des propriétés des films magnétiques nanostructures pour des applications en dispositifs magnéto-acoustiques et spintroniques

摘要

Nowadays, structures based on ferromagnetic materials are largely used for different applications: random access magneto-resistive memories, magnetic sensors, and also new electronic components and spintronic devices. The general trend of modern electronic is the reduction of dimensions down to submicronic scales. Therefore, the magnetic nanostructures are of great interest and their methods of fabrication and properties largely studied.The main goal of this work is the preparation and experimental and theoretical research on properties of magnetic nanostructures for applications in magnetoresistive and photonic devices. The Scanning Probe Lithography (SPL) and Electron Beam Lithography (EBL) were used for the nanostructures fabrications. First steps were also achieved in fabrication of phononic cristals sensitive the magnetic field.
