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.
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…

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…

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…
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 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…
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…
Physical Review B
Abstract: We report a study of the Fermi surface of the chiral semimetal CoSi and its relationship to a network of multifold topological crossing points, Weyl points, and topological nodal planes in the…
Physical Review B
Abstract: We present a study of the lattice dynamical properties of Mn1-xFexSi with 0≤x≤0.22. Employing time-of-flight neutron spectroscopy and inelastic x-ray scattering, we investigate the doping dependence…
Physical Review Applied
Abstract: A key challenge for the realization of future skyrmion devices comprises the controlled creation, annihilation, and detection of these topologically nontrivial magnetic textures. In this study, we…
Journal of Physics Condensed Matter
Abstract: We advertise rare-earth intermetallics with high-symmetry crystal structures and competing interactions as a possible materials platform hosting spin structures with non-trivial topological…
