Theoretical investigation of the influence of adsorbed molecules on the magnetic anisotropy of magnetic thin films

Contact: BARRETEAU Cyrille, , cyrille.barreteau@cea.fr, +33 1 69 08 38 56
Summary:
In this internship we propose to study via electronic structure methods (ab-initio and/or tight-binding) the magnetic anisotropy of few simple systems. We will first consider cobalt and iron thin films in interaction with carbon monoxide. More complex systems will be further investigated. The final goals is to find systems molecule/substrate with optimal properties in view of possible applications.
Possibility of continuation in PhD: Oui
Deadline for application:22/03/2018

Full description:
Nanomagnetism is an active field at the frontier of various domains. It consists in the study (and use) of the magnetism of nanometer sized systems. Magnetic properties of nano-objects generally strongly differ from their bulk counterpart. A major issue is to control/manipulate their magnetic properties. One of the fundamental properties of magnetic materials is their magnetic anisotropy which is characterized by their easy axis. It has been recently demonstrated that the interaction between a magnetic thin film and adsorbed molecules can greatly modify the anisotropy of the film due to hybridization between the molecule and the surface atoms of the substrate

The final goals is to find systems molecule/substrate with optimal properties in view of possible applications. This internship can be pursued by a PhD in the context of a European project involving 6 partners from various EU countries (France, Denmark, Germany, Spain)
