Origin of Ising magnetism in Ca3Co2O6 unveiled by orbital imaging
Brett Leedahl, Martin Sundermann, Andrea Amorese +7
The one-dimensional cobaltate Ca3Co2O6 is an intriguing material having an unconventional magnetic structure, displaying quantum tunneling phenomena in its magnetization. Using a n…
Natural-Orbital Impurity Solver and Projection Approach for Green's Function
Y. Lu, X. Cao, P. Hansmann +1
We extend a previously proposed rotation and truncation scheme to optimize quantum Anderson impurity calculations with exact diagonalization [PRB 90, 085102 (2014)] to density-matr…
Nature of the magnetism of iridium in the double perovskite Sr2CoIrO6
S. Agrestini, K. Chen, C. -Y. Kuo +12
We report on our investigation on the magnetism of the iridate double perovskite SrCoIrO, a nominally Ir Van Vleck system. Using x-ray absorption (XAS) a…
Resonant inelastic x-ray scattering study of bond order and spin excitations in nickelate thin-film structures
K. Fürsich, Y. Lu, D. Betto +13
We used high-resolution resonant inelastic x-ray scattering (RIXS) at the Ni edge to simultaneously investigate high-energy interband transitions characteristic of Ni-O bond…
Direct imaging of orbitals in quantum materials
Hasan Yavaş, Martin Sundermann, Kai Chen +5
The spectacular physical properties of quantum materials based on transition metal, rare earth, and actinide elements continue to challenge our comprehension of solid state physics…
Orientation of ground-state orbital in CeCoIn and CeRhIn
M. Sundermann, A. Amorese, F. Strigari +10
We present core level non-resonant inelastic x-ray scattering (NIXS) data of the heavy fermion compounds CeCoIn and CeRhIn measured at the Ce -edges. The higher th…
