Evolution of electron spin resonance through a metallic quantum critical phase diagram
Marc Scheffler, Jörg Sichelschmidt, Conrad Clauss +6
In the heavy-fermion metal YbRh2Si2, quantum criticality at a suppressed antiferromagnetic order is governed by the interplay of local magnetic moments and itinerant conduction ele…
Multilayer Crystal Field states from locally broken centrosymmetry
Owen Moulding, Makoto Shimizu, Amit Pawbake +9
Local charge, spin, or orbital degrees of freedom with intersite interactions are oftentimes sufficient to construct most quantum orders. This is conventionally true for f-electron…
Magnetic Phase Diagram of YbRh\textsubscript{2}Si\textsubscript{2}: the Influence of Hyperfine Interactions
Jan Knapp, Lev V. Levitin, Jan Nyeki +6
We report the determination of the magnetic phase diagram of the heavy fermion metal YbRh\textsubscript{2}Si\textsubscript{2} in magnetic fields up to 70\,mT applied perpendicular…
Coexistence of local magnetism and superconductivity in the heavy-fermion CeRhAs revealed by SR studies
Seunghyun Khim, Oliver Stockert, Manuel Brando +8
The superconducting (SC) state ( = 0.3 K) of the heavy-fermion compound CeRhAs, which undergoes an unusual field-induced transition to another high-field SC s…
Metallic local-moment magnetocalorics as a route to cryogenic refrigeration
Thomas Gruner, Jiasheng Chen, Dongjin Jang +4
Commercial adiabatic demagnetisation refrigerators still employ the same hydrated salts that were first introduced over 85 years ago. The inherent limitations of these insulating m…
Pressure-tuned quantum criticality in the locally non-centrosymmetric superconductor CeRhAs
Meike Pfeiffer, Konstantin Semeniuk, Javier F. Landaeta +6
The unconventional superconductor CeRhAs (critical temperature ) displays an exceptionally rare magnetic-field-induced transition betw…
CeIrGa : a new locally non-centrosymmetric heavy fermion system
Arushi, Raul Cardoso-Gil, Christoph Geibel
Recently, a new type of unconventional superconductivity with a field-induced transition between two different superconducting (SC) states was discovered in the heavy fermion syste…
Temperature- and Magnetic-Field-Dependent Optical Properties of Heavy Quasiparticles in YbIr2Si2
T. Iizuka, S. Kimura, A. Herzog +4
We report the temperature- and magnetic-field-dependent optical conductivity spectra of the heavy electron metal YbIrSi. Upon cooling below the Kondo temperature ($T_{\rm K…
Quantum Griffiths phase in CePd(1-x)Rh(x) with x ~ 0.8
M. Brando, T. Westerkamp, M. Deppe +3
The magnetic field dependence of the magnetisation () and the temperature dependence of the ac susceptibility () of CePd(1-x)Rh(x) single crystals with $0.80 \leq x…
ESR of YbRh2Si2 and 174YbRh2Si2 : local and itinerant properties
J. Wykhoff, J. Sichelschmidt, G. Lapertot +7
Below the Kondo temperature the heavy Fermion compound YbRhSi shows a well defined Electron Spin Resonance (ESR) with local Yb properties. We report a detailed a…
Experimental evidence for a spin-Peierls-transition in
M. Weiden, R. Hauptmann, C. Geibel +4
We present the first measurements of magnetisation and Raman light scattering on single crystals. Below 34 K, we observe a pronounced isotropic decrease of the suscep…
