Rotational symmetry breaking at the incommensurate charge-density-wave transition in Ba(Ni,Co)(As,P): Possible nematic phase induced by charge/orbital fluctuations
Michael Merz, Liran Wang, Thomas Wolf +3
Nematic phase transitions in high-temperature superconductors have a strong impact on the electronic properties of these systems. BaFeAs,\@ with an established nematic tran…
Evolution of nematic fluctuations in CaK(FeNi)As with spin-vortex crystal magnetic order
Anna E. Böhmer, Fei Chen, William R. Meier +11
The CaK(FeNi)As superconductors resemble the archetypal 122-type iron-based materials but have a crystal structure with distinctly lower symmetry. This fa…
On the microscopic origin of reversible and irreversible reactions of LiNixCoyMnx cathode materials: Ni-O hybrid bond formation vs. cationic and anionic redox
Karin Kleiner, Claire A. Murray, Cristina Grosu +5
Energy density limitations of layered oxides with different Ni contents, i.e., of the conventional cathode materials in Li-ion batteries, are investigated across the first discharg…
Vortex-lattice melting and paramagnetic depairing in the nematic superconductor FeSe
F. Hardy, L. Doussoulin, T. Klein +9
The full H-T phase diagram in the nematic superconductor FeSe is mapped out using specific-heat and thermal-expansion measurements down to 0.7 K and up to 30 T for both field direc…
Observation of a possible diluted ferromagnetism above room temperature in cobalt-substituted LaTa(O,N)3-d
Cora Bubeck, Eberhard Goering, Robert Lawitzki +11
Since 2000, the intensive effort in materials research to develop a diluted magnetic semiconductor exhibiting high-temperature (HT) ferromagnetism above room temperature was not su…
Band Engineering of Dirac cones in Iron Chalcogenides
Lars Lauke, Rolf Heid, Michael Merz +3
By band engineering the iron chalcogenide Fe(Se,Te) via ab-initio calculations, we search for topological surface states and realizations of Majorana bound states. Proposed topolog…
