Quantum Oscillations of the Quasiparticle Lifetime in a Metal
Nico Huber, Valentin Leeb, Andreas Bauer +4
Following nearly a century of research, it remains a puzzle that the low-lying excitations of metals are remarkably well explained by effective single-particle theories of non-inte…
Optical creation and annihilation of skyrmion patches in a bulk chiral magnet
Jantje Kalin, Sibylle Sievers, Daniel Kalin +6
A key challenge for the realization of future skyrmion devices comprises the controlled creation, annihilation and detection of these topologically non-trivial magnetic spin textur…
Resonant elastic X-ray scattering of antiferromagnetic superstructures in EuPtSi
Wolfgang Simeth, Andreas Bauer, Christian Franz +6
We report resonant elastic X-ray scattering (REXS) of long-range magnetic order in EuPtSi, combining different scattering geometries with full linear polarization anal…
Evolution of the spin dynamics during freezing in the spin-glass FeCr
Steffen Säubert, Christian Franz, Johanna K. Jochum +5
In the iron--chromium system, FeCr, a wide dome of spin-glass behavior emerges when the ferromagnetism of iron is suppressed and the antiferromagnetism of chromium em…
Optimization strategies and artefacts of time-involved small angle neutron scattering experiments
Denis Mettus, Alfonso Chacon, Andreas Bauer +2
Kinetic small-angle neutron scattering provides access to the microscopic properties of mesoscale systems under slow, periodic perturbations. By interlocking the phases of neutron…
Magnetic properties of the noncentrosymmetric tetragonal antiferromagnet EuPtSi
A. Bauer, A. Senyshyn, R. Bozhanova +6
We report a comprehensive study of single crystals of the noncentrosymmetric rare-earth compound EuPtSi grown by the optical floating-zone technique. Measurements of the magn…
