Our interest in magnetism is long-standing and extensive. We investigate the magnetic properties of transition and rare-earth metals in bulk, multilayer, surface and cluster geometries. We also study the magnetism of novel superconductors, complex oxides and dilute magnetic semiconductors.


ultrafast dynamics

We have recently developed an interest in the dynamical properties of magnetic materials, which is essential for the description of processes such as ultrafast demagnetization.

As part of our work, we have also developed the UppASD code, which we have used, for example, to investigate the properties of ferromagnets in the monolayer limit.

Model Magnetism

We also employ analytical methods to investigate model Hamiltonians that shed light, for example, on spin-polarized tunneling spectroscopy experiments.

Correlated Electronic Structures

Correlated Electronic Structures

Actinides and transition metal oxides are examples of highly correlated electronic structures. We study such systems using dynamical mean field theory (DMFT), in combination with a full-potential electronic structure method based on linear muffin-tin orbitals (the RSPt code).

The multipole expansion of the Hubbard-U interaction term is explicitly considered in our work based on linear augmented plane-wave method (the Elk code).

High moment materials for writer heads

High magnetic moment materials are essential for writer heads of hard disks. This project, in collaboration with Seagate Technology, Ireland and University of Duisburg, Germany, funded by EU deals with the development of high moment materials. The idea is to combine rare earth and transition metal elements to realize large magnetic moments stabilized at high temperatures in a single material.
