Dimensionality-driven metal-insulator-transition in spin-orbit coupled SrIrO
P. Schütz, D. Di Sante, L. Dudy +10
Upon reduction of the film thickness we observe a metal-insulator transition in epitaxially stabilized, spin-orbit coupled SrIrO ultrathin films. By comparison of the experimen…
Electronic reconstruction at the isopolar LaTiO3/LaFeO3 interface: An x-ray photoemission and density functional theory study
J. E. Kleibeuker, Z. Zhong, H. Nishikawa +8
We report the formation of a non-magnetic band insulator at the isopolar interface between the antiferromagnetic Mott-Hubbard insulator LaTiO3 and the antiferromagnetic charge tran…
Bulk Nature of Layered Perovskite Iridates beyond the Mott Scenario : An Approach from Bulk Sensitive Photoemission Study
A. Yamasaki, S. Tachibana, H. Fujiwara +24
We present genuine bulk Ir 5d jeff states of layered perovskite iridates obtained by hard-x-ray photoemission spectroscopy (HAXPES) with s- and p-polarized lights. HAXPES spectra o…
Polaron physics and crossover transition in magnetite probed by pressure-dependent infrared spectroscopy
J. Ebad-Allah, L. Baldassarre, M. Sing +3
The optical properties of magnetite at room temperature were studied by infrared reflectivity measurements as a function of pressure up to 8 GPa. The optical conductivity spectrum…
Unoccupied electronic structure of TiOCl studied by x-ray absorption near-edge spectroscopy
Sebastian Glawion, Maurits W. Haverkort, Götz Berner +6
We study the unoccupied electronic structure of the spin-1/2 quantum magnet TiOCl by x-ray absorption near-edge spectroscopy (XANES) at the Ti L and O K edges. Data is acquired bot…
Two-Spinon and Orbital Excitations of the Spin-Peierls System TiOCl
Sebastian Glawion, Jakoba Heidler, Maurits W. Haverkort +8
We combine high-resolution resonant inelastic x-ray scattering with cluster calculations utilizing a recently derived effective magnetic scattering operator to analyze the polariza…
Heat conductivity of the spin-Peierls compounds TiOCl and TiOBr
N. Hlubek, M. Sing, S. Glawion +5
We report experimental results on the heat conductivity κof the S=1/2 spin chain compounds TiOBr and TiOCl for temperatures 5K<T<300K and magnetic fields up to 14. Surprisingly, we…
Incommensurate structure of the spin-Peierls compound TiOCl
A. Krimmel, J. Strempfer, B. Bohnenbuck +8
We report on a detailed single crystal x-ray diffraction study of the unconventional spin-Peierls compound TiOCl. The intermediate phase of TiOCl is characterized by an incommensur…
High-energy photoemission on Fe3O4: Small polaron physics and the Verwey transition
D. Schrupp, M. Sing, M. Tsunekawa +7
We have studied the electronic structure and charge ordering (Verwey) transition of magnetite (Fe3O4) by soft x-ray photoemission. Due to the enhanced probing depth and the use of…
