Interplay between Superconductivity and Magnetism in Rb0.8Fe1.6Se2 under Pressure
Vadim Ksenofontov, Sergey A. Medvedev, Leslie M. Schoop +6
High-pressure magnetization, structural and 57Fe Mössbauer studies were performed on superconducting Rb0.8Fe1.6Se2.0 with Tc = 32.4 K. The superconducting transition temperature gr…
Actinide Topological Insulator Materials with Strong Interaction
Xiao Zhang, Haijun Zhang, Claudia Felser +1
Topological band insulators have recently been discovered in spin-orbit coupled two and three dimensional systems. In this work, we theoretically predict a class of topological Mot…
Electronic structure and symmetry of valence states of epitaxial NiTiSn and NiZrHfSn thin films by hard x-ray photoelectron spectroscopy
Xeniya Kozina, Tino Jaeger, Siham Ouardi +7
The electronic band structure of thin films and superlattices made of Heusler compounds with NiTiSn and NiZrHfSn composition was studied by means of polarization de…
Berry-curvatures and anomalous Hall effect in Heusler compounds
Jurgen Kubler, Claudia Felser
Berry curvatures are computed for a set of Heusler compounds using density functional (DF) calculations and the wave functions that DF provide. The anomalous Hall conductivity is o…
Comparison of two structures for transition-metal-based half Heusler alloys exhibiting fully compensated half metallicity
Michael Shaughnessy, C. Y. Fong, Lin H. Yang +1
We search for new fully compensated half metals, in which only one electronic spin channel is conducting and there exists no net magnetic moment. We focus on half Heusler alloys an…
Systematical, experimental investigations on LiMgZ (Z= P, As, Sb) wide band gap semiconductors
Andreea Beleanu, Mihail Mondeshki, Quin Juan +3
This work reports on the experimental investigation of the wide band gap compounds LiMgZ (Z = P, As, Sb), which are promising candidates for opto-electronics and anode materials fo…
