Hidden structural transition in epitaxial CaSrIrO/SrTiO thin film
W. T. Jin, H. Gretarsson, S. Y. Jang +3
A structural transition in an ABO perovskite thin film involving the change of the BO octahedral rotation pattern can be hidden under the global lattice symmetry impose…
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…
Observation of spin-orbit excitations and Hund's multiplets in CaRuO
H. Gretarsson, H. Suzuki, Hoon Kim +6
We use Ru -edge (2838.5 eV) resonant inelastic x-ray scattering (RIXS) to quantify the electronic structure of CaRuO, a layered -electron compound that exhibits a…
Magnetic excitations in hole-doped Sr2IrO4: A comparison with electron-doped cuprates
J. P. Clancy, H. Gretarsson, M. H. Upton +3
We have studied the evolution of magnetic and orbital excitations as a function of hole-doping in single crystal samples of Sr2Ir(1-x)Rh(x)O4 (0.07 < x < 0.42) using high resolutio…
Spin waves and spin-state transitions in a ruthenate high-temperature antiferromagnet
