Bio

After studies at the royal institute of technology (KTH) in Stockholm, Sweden, I received my PhD in physics from Uppsala University in 2016. During my PhD studies, I used first principles calculations, and related computational methods, to investigate the magnetic properties of transition metal compounds for permanent magnet applications. This research led to new insights in how one can tune the magnetic properties, with focus on magnetocrystalline anisotropy, in such materials, with possible high importance for green technologies. I also studied magnetic effects in electron scattering processes, leading the way towards new methods of imaging magnetic materials, with extremely high spatial resolution, using transmission electron microscopy.

Next, I did postdoctoral research at the ETH in Zürich, Switzerland. During this time I expanded my expertise from magnetism towards ferroelectric and multiferroic materials. Using first principles based modelling, I showed how enormous magnetoelectric coupling can be achieved near a so called tetracritical point, which can practically be found, e.g., by strain engineering the perovskite compound SrMnO3. I also showed that such a point allows for new exciting phenomena within the are of solid state cooling. In particular, a strong cross-caloric magnetic contribution to the electrocaloric effect was predicted.

Most recently, I received an international post-doc grant from the Swedish research council (VR), to join ICMAB for 2-3 years. During my time here, I will use first principles theory to investigate strain-gradient induced magnetic phenomena, aiming at developing the new research field of flexomagnetism.
