Nematicity in LaFeAsO single crystals studied by elastoresistance, high-resolution thermal expansion and shear-modulus measurements
X. C. Hong, S. Sauerland, L. Wang +10
Nematicity in LaFeAsO single crystals is studied by means of high-resolution thermal expansion, shear modulus, and elastoresistivity measurements. A softening of the shear modulus…
Revisiting the phase diagram of LaFeCoAsO on single crystals by thermodynamic methods
Francesco Scaravaggi, Sven Sauerland, Liran Wang +13
In this work we revisit the phase diagram of Co-doped LaFeAsO using single crystals and thermodynamic methods. From magnetic susceptibility studies we track the doping evolution of…
Mapping out the spin fluctuations in Co-doped LaFeAsO single crystals by NMR
Piotr Lepucki, Raphael Havemann, Adam P. Dioguardi +7
We determine the phase diagram of LaFeCoAsO single crystals by using nuclear magnetic resonance (NMR). Up to a nominal doping of , it follows the phase diagram…
Evolution of the nematic susceptibility in LaFeCoAsO
Xiaochen Hong, Federico Caglieris, Rhea Kappenberger +8
The identification of electronic nematicity across series of iron-based superconductors raises the question of its relationship with superconductivity and other ordered states. Her…
Berry curvature unravelled by the Nernst effect in MnGe
Christoph Wuttke, Federico Caglieris, Steffen Sykora +8
The discovery of topological quantum materials represents a striking innovation in modern condensed matter physics with remarkable fundamental and technological implications. Their…
Chemical Aspects of the Antiferromagnetic Topological Insulator MnBiTe
Alexander Zeugner, Frederik Nietschke, Anja U. B. Wolter +25
Crystal growth of MnBiTe has delivered the first experimental corroboration of the 3D antiferromagnetic topological insulator state. Our present results confirm that th…
