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…
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…
Low-temperature antiferromagnetic order in orthorhombic CePdAl
Vivek Kumar, Andreas Bauer, Christian Franz +6
We report the magnetization, ac susceptibility, and specific heat of optically float-zoned single crystals of CePdAl. In comparison to the properties of polycrystalline CePdA…
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…
Small-angle neutron scattering of long-wavelength magnetic modulations in reduced sample dimensions
Grace L. Causer, Alfonso Chacon, André Heinemann +1
Magnetic small-angle neutron scattering (SANS) is ideally suited to provide direct, reciprocal-space information of long-wavelength magnetic modulations, such as helicoids, soliton…
Neutron Depolarization due to Ferromagnetism and Spin Freezing in CePdRh
M. Seifert, P. Schmakat, M. Schulz +5
We report neutron depolarization measurements of the suppression of long-range ferromagnetism and the emergence of magnetic irreversibilities and spin freezing in CePdRh$_x…
