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…
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…
Orbital-Resolved Partial Charge Transfer from the Methoxy Groups of Substituted Pyrenes in Complexes with Tetracyanoquinodimethane - a NEXAFS Study
K. Medjanik, S. A. Nepijko, H. J. Elmers +7
It is demonstrated that the near-edge X-ray absorption fine structure (NEXAFS) provides a powerful local probe of functional groups in novel charge transfer (CT) compounds. Microcr…
Crystal and magnetic structure of La_{1-x}Sr_{1+x}MnO_{4} : role of the orbital degree of freedom
D. Senff, P. Reutler, M. Braden +7
The crystal and magnetic structure of La_{1-x}Sr_{1+x}MnO_4 (0<x<0.7) has been studied by diffraction techniques and high resolution capacitance dilatometry. There is no evidence f…
