Objectives of the Project

Objectives of the Project

In order to address the issues raised in introducing the concept of the project, and to ensure that the theoretical and modelling developments have the strongest interaction with experiments, we have formulated the following objectives:

  • Obtain fundamental knowledge of dynamic processes on the fs timescale; this requires the development of new approaches to treat non-equilibrium electron dynamics, utilizing Spin Density Functional Theory (SDFT), developing time dependent SDFT beyond linear response techniques and applying these to understand the fundamental mechanisms.
  • Advanced atomistic models; this includes spin models with equations of motion beyond Langevin dynamics; new approaches to induced spins and transport; integration of thermodynamic and quantum approaches.
  • Mesoscopic model development; this requires mesoscopic modelling using a generalised Landau-Lifshitz-Bloch (LLB) equation; formulation for ferrimagnets and determination of LLB parameters from SDFT calculations and atomistic models.
  • Multiscale calculations and link to experiments; verification of models against experiment; feedback from experiments to model development; material studies; large-scale calculations and device simulations.
  • Detailed materials studies; candidate materials with especially promising properties on the femtosecond timescale will include ferromagnets, ferrimagnets, and antiferromagnets. Effects of nanostructuring will be included. Emphasis will be placed on studies of itinerant ferromagnets such as Ni to understand the basic physics of ultrafast reversal, and of layered and/or multi-component magnetic materials such as FePt, FeNi, and GdFeCo, which are important from an industrial point of view, for example, for Heat Assisted Magnetic Recording (HAMR) or Opto-Magnetic recording. Antiferromagnetic materials will be included from the viewpoint of their intrinsic ultrafast (THz) dynamics.

The individual knowledge and skills of each of the members of the consortium and industrial partners will be utilized to complete the objectives proposed in this project.

The Work Packages

The FEMTOSPIN project, like all EU framework 7 projects are well structured into sections that have common aims or outcomes. This divides up the work into manageable chunks known as work packages. These work packages can include different kinds of activity, for example, management of the project or scientific tasks. The lead institution is responsible for overseeing that the work packages are carried out. Each work package also has a leader responsible for ensuring that the work that is allocated within the work package is carried out and that the "deliverables" are reached.*/

In the femtospin project there are 7 work packages; 5 (research and technological development (RTD), 1 management (MGT) and 1 other.
