Multiscale Modelling of Femtosecond Spin Dynamics



The femtospin project is a collaborative project supported by the European Commission under the Environment (including climate change) Theme of the 7th Framework Programme for Research and Technological Development.

Aims of the Project

The overriding aim of the project is to build a strong multiscale theoretical and computational framework for research into ultrafast spin manipulation in nanostructured magnetic materials. This theoretical framework will be developed alongside state of the art experimental programmes. The collaboration between advanced theory and computational modelling of realistic systems and novel, cutting edge experiments, in both of which the collaboration excels, will lead to a deeper understanding of the fundamental physics of spin ordered materials. Such collaboration will lead to the development of advanced computational tools for the design of a new generation of materials for applications in ultrafast devices. This is an important and difficult challenge, as it spans multiple timescales (from femtoseconds to nanoseconds) and it involves the creation of interfaces between electronic structures calculations, atomistic models and mesoscopic simulations that jointly form the required multiscale approach.

The project includes the important task of relating the theoretical predictions to experimental studies in order to verify the physical basis of the models and advise experimental developments in a rapidly moving field. To achieve these aims we have assembled a multidisciplinary consortium of leading theoretical and experimental groups along with important potential industrial users of ultrafast magnetic and spintronic technology. The theory groups have proven track records in computational methods spanning all length-scales from electronic structure calculations to mesoscopic models and the experimental groups constitute the forefront of femtosecond optical and X-ray measurements on magnetic materials. The industrial partners are important end users of the technology.
