High-Resolution Capacitance Dilatometry of Microscopically Thin Samples Using a Miniature Dilatometer
R. Küchler, S. Panja, S. Wirth +1
We present a novel application of our high-resolution capacitance dilatometer, specifically engineered for the precise characterization of quantum materials. These materials, which…
1/5 and 1/3 magnetization plateaux in the spin 1/2 chain system YbAlO3
P. Mokhtari, S. Galeski, U. Stockert +7
Quasi-one-dimensional magnets can host an ordered longitudinal spin-density wave state (LSDW) in magnetic field at low temperature, when longitudinal correlations are strengthened…
Coupling between magnetic and thermodynamic properties in RhSi ( = Dy, Ho)
H. Dawczak-Dębicki, Kristin Kliemt, M. Victoria Ale Crivillero +4
Single crystals of DyRhSi and HoRhSi were investigated by thermal expansion and magnetostriction. The different types of magnetic order can clearly be seen in these…
New applications for the world's smallest high-precision capacitance dilatometer and its stress-implementing counterpart
R. Kuchler, R. Wawrzynczak, H. Dawczak-Debicki +2
We introduce a new stress dilatometer with exactly the same size and weight as the world's smallest miniature capacitance dilatometer (height x width x depth = 15 mmx14 mmx15 mm, w…
Possible quadrupole density wave in the superconducting Kondo lattice CeRh2As2
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,…
Origin of the quasi-quantized Hall effect in ZrTe5
Stanislaw Galeski, Toni Ehmcke, Rafal Wawrzynczak +24
The quantum Hall effect (QHE) is traditionally considered a purely two-dimensional (2D) phenomenon. Recently, a three-dimensional (3D) version of the QHE has been reported in the D…
Quantum Tricritical Points in NbFe
Sven Friedemann, Will J Duncan, Max Hirschberger +6
Quantum critical points (QCPs) emerge when a 2nd order phase transition is suppressed to zero temperature. In metals the quantum fluctuations at such a QCP can give rise to new pha…
Sequential localization of a complex electron fluid
V. Martelli, A. Cai, E. M. Nica +13
Complex and correlated quantum systems with promise for new functionality often involve entwined electronic degrees of freedom. In such materials, highly unusual properties emerge…
Cascade of magnetic field induced Lifshitz transitions in the ferromagnetic Kondo lattice material YbNi4P2
H. Pfau, R. Daou, S. Friedemann +11
A ferromagnetic quantum critical point is thought not to exist in two and three-dimensional metallic systems yet is realized in the Kondo lattice compound YbNi4(P,As)2, possibly du…
A uniaxial stress capacitive dilatometer for high-resolution thermal expansion and magnetostriction under multiextreme conditions
R. Kuechler, C. Stingl, P. Gegenwart
Thermal expansion and magnetostriction are directional dependent thermodynamic quantities. For the characterization of novel quantum phases of matter it is required to study materi…
k=0 magnetic structure and absence of ferroelectricity in SmFeO3
C. -Y. Kuo, Y. Drees, M. T. Fernández-Díaz +17
SmFeO3 has attracted considerable attention very recently due to the reported multiferroic properties above room-temperature. We have performed powder and single crystal neutron di…
Low temperature thermodynamic properties near the field-induced quantum critical point in DTN
Franziska Weickert, Robert Kuechler, Alexander Steppke +10
We present a comprehensive experimental and theoretical investigation of the thermodynamic properties: specific heat, magnetization and thermal expansion in the vicinity of the fie…

T. Westerkamp, M. Deppe, R. Kuechler +5
We report on a comprehensive study of CePdRh poly- and single crystals close to the ferromagnetic instability by means of low-temperature ac su…
Quantum Criticality in doped CePd_1-xRh_x Ferromagnet
J. G. Sereni, T. Westerkamp, R. Kuechler +3
CePd_1-xRh_x alloys exhibit a continuous evolution from ferromagnetism (T_C= 6.5 K) at x = 0 to a mixed valence (MV) state at x = 1. We have performed a detailed investigation on t…
