Scientific activities covered at our institute include the fundamental properties of magnetic and superconducting materials (bulk compounds and thin films), materials science and a few selected problems in particle physics. The institute has a long tradition in neutron related research, notably the development of state-of-the-art neutron scattering techniques. Amongst other contributions we provide the scientific partnership of TUM for the beam lines Reseda, Mira, Antares and Nepomuc at FRM II. In addition we operate a number of laboratories at the Physik-Department that are focussed on studies of bulk properties under extreme conditions, materials preparation and materials characterisation.
Science Advances
Abstract: Spin textures are magnetic configurations that vary smoothly in space, momentum, or time. This review explores the topology, geometry, dynamics, and imaging of these complex, often noncollinear…
Journal of Applied Crystallography
Abstract: The magnetic excitations of the skyrmion lattice in MnSi comprise a multitude of individual modes, which are non-reciprocal and thereby propagate unidirectionally. We report inelastic neutron…
Review of Scientific Instruments
Abstract: We developed an optically detected magnetic resonance setup designed for compatibility with a widely used, commercially available helium bath cryostat equipped with a variable temperature insert. The…
Physical Review Applied
Abstract: Magnetic skyrmions are spin textures with nontrivial topology that form two-dimensional hexagonal lattices (SkX) in chiral magnets. Element-specific reciprocal-space characterization of skyrmion…
Applied Physics Letters
Abstract: We present a temperature-modulated de Haas–van Alphen measurement technique that allows selective addressing of quantum oscillations with different effective masses m ∗ using a non-monotonic amplitude…
Physical Review B
Abstract: Inelastic neutron scattering in the chiral magnet Cu2OSeO3 reveals strong nonreciprocal effects on magnon propagation at the boundary of the nuclear Brillouin zone. The nonreciprocal response is…
Proceedings of the National Academy of Sciences of the United States of America
Abstract: In three-dimensional chiral magnets, skyrmions are line-like objects oriented parallel to the applied magnetic field. The efficient coupling of magnetic skyrmion lattices to spin currents and magnetic…
Journal of Applied Crystallography
Abstract: We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time-of-flight (ToF) spectroscopy, a conventional neutron scattering method. The…
Physical Review B
Abstract: We study the electronic structure of the chiral semimetal PdGa by means of the de Haas–van Alphen and Shubnikov–de Haas effect. We find that the Fermi surface of PdGa comprises multiple pockets split…
Journal of Physics Condensed Matter
Abstract: Diborides A B 2 crystallizing in the hexagonal C32 structure exhibit a wide range of magnetic and electronic properties depending on the choice of the element A and the precise values of the lattice…
