Microstructuring YbRh2Si2 for resistance and noise measurements down to ultra-low temperatures
Alexander Steppke, Sandra Hamann, Markus König +9
The discovery of superconductivity in the quantum critical Kondo-lattice system YbRh2Si2 at an extremely low temperature of 2 mK has inspired efforts to perform high-resolution ele…
Two-carrier Magnetoresistance: Applications to CaRuO
Lakshmi Das, Yang Xu, Tian Shang +13
Ambipolar transport is a commonly occurring theme in semimetals and semiconductors. Here we present an analytical formulation of the conductivity for a two-band system. Electron an…
The relationship between transport anisotropy and nematicity in FeSe
Jack Bartlett, Alexander Steppke, Suguru Hosoi +6
The mechanism behind the nematicity of FeSe is not known. Through elastoresitivity measurements it has been shown to be an electronic instability. However, so far measurements have…
Field-induced double dome and Bose-Einstein condensation in the crossing quantum spin chain system AgVOAsO4
Franziska Weickert, Adam A. Aczel, Matthew B. Stone +11
We present inelastic neutron scattering data on the quantum paramagnet AgVOAsO4 that establish the system is a S=1/2 alternating spin chain compound and provide a direct measuremen…
Emergence of superconductivity in the canonical heavy-electron metal YbRh2Si2
Erwin Schuberth, Marc Tippmann, Lucia Steinke +8
We report magnetic and calorimetric measurements down to T = 1 mK on the canonical heavy-electron metal YbRh2Si2. The data reveal the development of nuclear antiferromagnetic order…
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…
