Multidimensional entropy landscape of quantum criticality
K. Grube, S. Zaum, O. Stockert +2
The Third Law of Thermodynamics states that the entropy of any system in equilibrium has to vanish at absolute zero temperature. At nonzero temperatures, on the other hand, matter…
Fermi volume evolution and crystal field excitations in heavy-fermion compounds probed by time-domain terahertz spectroscopy
Shovon Pal, Christoph Wetli, Farzaneh Zamani +4
We measure the quasiparticle weight in the heavy-fermion compound CeCuAu () by time-resolved THz spectroscopy for temperatures from 2 up to 300\,K. This me…
Competing magnetic correlations across the ferromagnetic quantum critical point in the Kondo system CeTiVGe: V NMR as a local probe
M. Majumder, W. Kittler, V. Fritsch +3
V nuclear magnetic resonance (NMR) and magnetization studies on CeTiVGe have been performed to explore the evolution from the ferromagnetic () to…
Magnetic and structural quantum phase transitions in CeCu6-xAux are independent
K. Grube, L. Pintschovius, F. Weber +9
The heavy-fermion compound CeCuAu has become a model system for unconventional magnetic quantum criticality. For small Au concentrations , the compound…
STM-induced surface aggregates on metals and oxidized silicon
Dominik Stöffler, Hilbert von Löhneysen, Regina Hoffmann
We have observed an aggregation of carbon or carbon derivatives on platinum and natively oxidized silicon surfaces during STM measurements in ultra-high vacuum on solvent-cleaned s…
Long-range spin-polarized quasiparticle transport in mesoscopic Al superconductors with a Zeeman splitting
F. Hübler, M. J. Wolf, D. Beckmann +1
We report on nonlocal transport in multiterminal superconductor-ferromagnet structures, which were fabricated by means of e-beam lithography and shadow evaporation techniques. In t…
