Uniaxial stress tuning of geometrical frustration in a Kondo lattice
R. Kuechler, C. Stingl, Y. Tokiwa +3
Hexagonal CeRhSn with paramagnetic moments on a distorted Kagome lattice displays zero-field quantum critical behavior related to geometrical frustration. We report high-resol…
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…
Reversible Tuning of the Collapsed Tetragonal Phase Transition in CaFe2As2 by Separate Control of Chemical Pressure and Electron Doping
K. Zhao, C. Stingl, R. S. Manna +2
Single crystals of Ca(Fe1-xRux)2As2 (0<x<0.065) and Ca1-yLay(Fe0.973Ru0.027)2As2 (0<y<0.2) have been synthesized and studied with respect to their structural, electronic and magnet…
Characteristic signatures of quantum criticality driven by geometrical frustration
Y. Tokiwa, C. Stingl, M. S. Kim +2
Geometrical frustration describes situations where interactions are incompatible with the lattice geometry and stabilizes exotic phases such as spin liquids. Whether geometrical fr…
Low-energy electronic properties of clean CaRuO: elusive Landau quasiparticles
M. Schneider, D. Geiger, S. Esser +8
We have prepared high-quality epitaxial thin films of CaRuO with residual resistivity ratios up to 55. Shubnikov-de Haas oscillations in the magnetoresistance and a tempe…
Electronic nematicity and its relation to quantum criticality in Sr_3Ru_2O_7 studied by thermal expansion
C. Stingl, R. S. Perry, Y. Maeno +1
We report high-resolution measurements of the in-plane thermal expansion anisotropy in the vicinity of the electronic nematic phase in SrRuO down to very low temperatur…
