Large off diagonal exchange couplings and spin liquid states in symmetric iridates
Ravi Yadav, Satoshi Nishimoto, Manuel Richter +2
Iridate oxides on a honeycomb lattice are considered promising candidates for realization of quantum spin liquid states. We investigate the magnetic couplings in a structural model…
Revised crystal structure and electronic properties of high dielectric Ba(FeNb)O ceramics
Rajyavardhan Ray, A. K. Himanshu, Golak K. Mandal +7
Ba(FeNb)O (BFN) ceramics are considered to be promising for technological applications owing to their high dielectric constant over a wide range of temperatures…
Dirac fermions and flat bands in the ideal kagome metal FeSn
Mingu Kang, Linda Ye, Shiang Fang +19
The kagome lattice based on 3d transition metals is a versatile platform for novel topological phases hosting symmetry-protected electronic excitations and exotic magnetic ground s…
Ba2NiOsO6: A Dirac-Mott insulator with ferromagnetism near 100 K
Hai L. Feng, Stuart Calder, Madhav Prasad Ghimire +14
The ferromagnetic semiconductor Ba2NiOsO6 (Tmag ~100 K) was synthesized at 6 GPa and 1500 °C. It crystallizes into a double perovskite structure [Fm-3m; a = 8.0428(1) Å], where the…
Magnetic-field induced band-structure change in CeBiPt
N. Kozlova, J. Hagel, M. Doerr +11
We report on a field-induced change of the electronic band structure of CeBiPt as evidenced by electrical-transport measurements in pulsed magnetic fields. Above ~25 T, the charge-…
