Short Biography

Frithjof Nolting received his Diploma in Physics at the University of Braunschweig in 1994, studying heavy fermion systems at low temperatures and high pressures, and his PhD in Physics at the University of Zürich in 1998, determining the gravitational constant supervised by Prof. Walter Kündig. In 1999 he started his work on magnetism at the nanoscale joining the group of Prof. Joachim Stöhr, Stanford University, and worked at the Advanced Light Source (ALS), Berkeley, and the Stanford Synchrotron Radiation Laboratory (SSRL). In 2001 he started working at the Swiss Light Source (SLS) and became in 2006 the group leader of the Microscopy and Magnetism group. In 2009 he was promoted to be a Titularprofessor at the University of Basel and since 2013 he is the head of the Laboratory for Synchrotron Radiation – Condensed Matter.

 

Research Summary

Exploring the world of reduced dimensions in solid state physics is a challenging and rewarding research area. When the dimensions reach the nanometer scale, surface, quantum mechanical and thermodynamic properties that are insignificant on macroscopic scales dominate more and more, resulting in new and interesting properties. In our work, we investigate the magnetic properties of nanoscale systems. Starting with systems where one dimension is on the nanoscale such as thin-film systems, and structuring them into "2D-nanosystems" we arrive at a system where all three dimensions are on the nanoscale: nanocrystals. Our current major research topics are opto-magnetism, spectroscopy of single nanomagnets, magnetization dynamics, artificially frustrated systems and artificial multiferroics. The measurements are performed static and time resolved with a pump-probe set-up and the primary investigation technique is polarization-dependent spectromicroscopy at the Swiss Light Source (SLS) which enables the element specific imaging of ferro- and antiferromagnetic domains in heterostructures.
