Origin of the non-Fermi-liquid behavior in CeRh2As2
P. Khanenko, D. Hafner, K. Semeniuk +11
Unconventional superconductivity in heavy-fermion systems appears often near magnetic quantum critical points (QCPs). This seems to be the case also for CeRh2As2 (Tc 0.31…
Physical properties of the ferromagnetic quantum critical system YbNi(PAs)
Kristin Kliemt, Jacintha Banda, Pavlo Khanenko +6
We report on single crystal growth and physical properties of the quantum critical Kondo-lattice system YbNi(PAs) with which hosts a ferromagn…
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…
Electronuclear Quantum Criticality
J. Banda, D. Hafner, J. F. Landaeta +6
We present here a rare example of electronuclear quantum criticality in a metal. The compound YbCu4.6Au0.4 is located at an unconventional quantum critical point (QCP). In this mat…
Decoupling multi-phase superconductivity from normal state ordering in CeRhAs
Konstantin Semeniuk, Daniel Hafner, Pavlo Khanenko +7
CeRhAs is a multi-phase superconductor with . The two superconducting (SC) phases, SC1 and SC2, observed for a magnetic field parallel…
Low-Temperature Thermal Conductivity of CeRhAs
Seita Onishi, Ulrike Stockert, Seunghyun Khim +3
CeRhAs is a rare unconventional superconductor ( K) characterized by two adjacent superconducting phases for a magnetic field -axis of the tetragon…

D. Hafner, P. Khanenko, E. -O. Eljaouhari +12
CeRh2As2 has recently been reported to be a rare case of multi-phase unconventional superconductor [S. Khim et al., arXiv:2101.09522] close to a quantum critical point (QCP). Here,…
Field-induced transition from even to odd parity superconductivity in CeRhAs
S. Khim, J. F. Landaeta, J. Banda +11
We report the discovery of two-phase unconventional superconductivity in CeRhAs. Using thermodynamic probes, we establish that the superconducting critical field of its hig…
Unconventional bulk superconductivity in YFeGe single crystals
Jiasheng Chen, Monika B. Gamża, Jacintha Banda +4
Using a new horizontal flux growth technique to produce high quality crystals of the unconventional superconductor YFeGe has led to a seven-fold reduction in disorder scatt…
Bulk properties of single crystals of the valence-unstable compound SmRhSi
Kristin Kliemt, Jacintha Banda, Christoph Geibel +2
We present the crystal growth as well as the structural, chemical and physical chracterization of SmRhSi single crystals. Their ground state is antiferromagnetic, as indica…
Ferromagnetic ordering along the hard axis in the Kondo lattice YbIr3Ge7
Binod K. Rai, Macy Stavinoha, J. Banda +7
Ferromagnetic Kondo lattice compounds are far less common than their antiferromagnetic analogs. In this work, we report the discovery of a new ferromagnetic Kondo lattice compound,…
Kondo-lattice ferromagnets and their peculiar order along the magnetically hard axis
Daniel Hafner, Binod K. Rai, Jacintha Banda +6
We show that Ce- and Yb-based Kondo-lattice ferromagnets order mainly along the magnetically hard direction of the ground state Kramers doublet determined by crystalline electric f…
Crystalline electric field of Ce in trigonal symmetry: CeIr3Ge7 as a model case
Jacintha Banda, Binod K. Rai, Helge Rosner +3
The crystalline electric field (CEF) of Ce3+ in trigonal symmetry has recently become of some relevance, for instance, in the search of frustrated magnetic systems. Fortunately, it…
CeIrGe: a local moment antiferromagnetic metal with extremely low ordering temperature
Binod K. Rai, Jacintha Banda, Macy Stavinoha +9
CeIrGe is an antiferromagnetic metal with a remarkably low ordering temperature = 0.63 K, while most Ce-based magnets order between 2 and 15 K. Thermodynamic an…
