The BME group developed the so-called Screened Korringa-Kohn-Rostoker (SKKR) method and computer code that has been widely adopted in the “electronic band-structure” community. In particular, the fully relativistic version of this code is highly suitable to study magnetism of surfaces, interfaces, thin films and finite atomic clusters. The activity of the group is associated with quite a number of studies related to magnetic anisotropies, electric and optical transport properties and ab initio spin-dynamics in magnetic multilayers and nanostructures. The BME group participated an international research consortium that was finalist in 2004 in the Descartes Prize of the European Union.

 

Role in the Network

BME will mainly focus on an extensive development of ab initio parameterisation of spin Hamiltonians used in multiscale spin-dynamics simulations. A suitable extension of the recently developed Spin-Cluster Expansion (SCE) technique will allow the calculation of biquadratic and multispin interactions of heterogeneous layered systems and finite nanoparticles. Longitudinal spin- fluctuations and induced spins will also be accounted in terms of calculations of the ordered magnetic phase at finite temperatures.
