Magnetic force microscopy beyond imaging - from low energy condensed matter physics to high energy particle physics

Magnetic force microscopy (MFM) - a scanning probe technique based on atomic force micros-copy - has established itself as a valuable tool to uncover magnetic domain structures and their formation on the sub-micrometer scale [1,2]. On the other hand, the magnetically coated tip can serve as a local probe to characterize important properties of superconducting samples. We have designed and constructed a low temperature, 3He magnetic force microscope operating within a three-axis vector magnet with field ranges of 2-2-9 T in x-y-z direction [3]. We demonstrate how to employ this system to investigate intrinsic properties of superconduc-tors, such as the pinning force of Abrikosov vortices, as well as the London penetration depth [4], which can yield valuable information about the superconducting gap symmetry. In addi-tion, we introduce the experimental realization of a model system to study quark confinement through Abrikosov vortices in superconductors [5].

Physik-Bachelor und -Master reakkreditiert

On the basis of the successful on-site review meeting in December 2015, the accreditation of our B.Sc. and M.Sc. 'Physics' was extended by ASIIN, thereby confirming the high quality of our study programs. - Meanwhile (as of 30 Sep 2016) the accreditation was extended until 2022, i.e., the maximally possible duration.
