Current projects

Magnetism in thin films, multilayers and heterostructures

In the Materials Physics group we specialize in growth and characterization of thin layered structures, mostly metallic. The main interest is fundamental research on magnetism.

My main current activity is in imaging of magnetic domains using Kerr microscopy. In this field I have a close collaboration with Dr. Rudolf Schäfer at IFW Dresden, Germany, funded by the STINT Institutional Grants Programme 2009-2014.

Films, multilayers and heterostructures are produced by sputtering under ultra-high vacuum conditions. Then they are characterized structurally by x-ray diffraction and reflectometry, and magnetically by e.g. magnetooptic Kerr effect (MOKE) measurements. We also collaborate with, e.g., the Solid State Physics division at the Department of Engineering Sciences, where additional magnetic characterizations can be performed. Collaboration with the Surface and Interface Science division at our own department has resulted in that I have done x-ray magnetic circular dichroism (XMCD) and resonant magnetic scattering (XRMS) measurements at e.g. MAX-Lab, Lund, Sweden.

Since 2006, I have occasionally used the neutron scattering facilities (LLB in Saclay and ILL in Grenoble), primarily for structural investigations on superlattices containing Fe and Co. The experiments in 2006-2008 were largely funded by travel grants from the Swedish Research Council.

A popular survey (in Swedish) of the magnetism in thin films can be found in the publication Kosmos 78 (2001) 77-114 (O. Eriksson, G. Andersson, O. Karis and P. Svedlindh), published by the Swedish Physical Society (Svenska fysikersamfundet).

Personal interests

Playing the cello (visit the Internet Cello Society for an experience of this lovely musical instrument!); third cello in chamber orchestra Mellersta Upplands Kammarorkester with about ten concerts a year.

Orienteering on a beginner's level, member of OK Linne (Uppsala). My main achievment here is that I completed all five days of the world's largest orienteering competition ("O-Ringen") in 2006 (D21M class) as well as in 2008 and 2010 (D35M class).

Reading, painting in oil and water colours and spending time outside with my children (born 1998 and 2001) and my husband.
