Nearest-neighbor Kitaev exchange blocked by charge order in electron doped -RuCl
A. Koitzsch, C. Habenicht, E. Mueller +9
A quantum spin-liquid might be realized in -RuCl, a honeycomb-lattice magnetic material with substantial spin-orbit coupling. Moreover, -RuCl is a Mott insulator,…
Plasmon Evolution and Charge-Density Wave Suppression in Potassium Intercalated Tantalum Diselenide
A. König, K. Koepernik, R. Schuster +4
We have investigated the influence of potassium intercalation on the formation of the charge-density wave (CDW) instability in 2H-tantalum diselenide by means of Electron Energy-Lo…
Electronic confinement and ordering instabilities in colossal magnetoresistive bilayer manganites
J. Trinckauf, T. Hänke, V. Zabolotnyy +11
We present angle-resolved photoemission studies of (La1-zPrz)2-2xSr1+2xMn2O7 with x=0.4 and z=0.1,0.2 and 0.4 along with density functional theory calculations and x-ray scattering…
Signatures of electronic polarons in LaSrMnO observed by electron energy-loss spectroscopy
R. Kraus, M. Schrade, R. Schuster +4
The dielectric properties of LaSrMnO single crystals with x = 0, 0.125, 0.25, and 0.5 were studied by means of electron energy-loss spectroscopy as a function o…
Investigation of the In-Gap Electronic Structure of LaAlO3 - SrTiO3 Heterointerfaces by Soft X-ray Spectroscopy
A. Koitzsch, J. Ocker, M. Knupfer +4
We investigated \LAO\ - \STO\ heterointerfaces grown either in oxygen rich or poor atmosphere by soft x-ray spectroscopy. Resonant photoemission across the Ti L absorption…
Anisotropic quasiparticle renormalization in Na0.73CoO2: role of inter-orbital interactions and magnetic correlations
J. Geck, S. V. Borisenko, H. Berger +8
We report an angular resolved photoemission study of Na0.73CoO2 where it is found that the renormalization of the quasiparticle (QP) dispersion changes dramatically upon a rotation…
