Electronic and magnetic excitations in the half-stuffed Cu-O planes of Ba2Cu3O4Cl2 measured by resonant inelastic x-ray scattering

Henrik Moodysson Rønnow, Peter Babkevich, Marco Grioni, Noore Elahi Shaik, Claudia Giuseppina Fatuzzo, Thorsten Schmitt, Bruce Normand, Sara Fatale

We use resonant inelastic x-ray scattering (RIXS) at the Cu L3 edge to measure the charge and spin excitations in the “half-stuffed” Cu-O planes of the cuprate antiferromagnet Ba2Cu3O4Cl2. The RIXS line shape reveals distinct contributions to the dd excita ...

Sputtering-induced reemergence of the topological surface state in Bi2Se3

Jan Hugo Dil, Stefan Peter Muff, Thorsten Schmitt, Vladimir N. Strocov

We study the fate of the surface states of Bi2Se3 under disorder with strength larger than the bulk gap, caused by neon sputtering and nonmagnetic adsorbates. We find that neon sputtering introduces strong but dilute defects, which can be modeled by a unit ...

Three-dimensional momentum-resolved electronic structure of 1T-TiSe2: A combined soft-x-ray photoemission and density functional theory study

Helmuth Berger, Thorsten Schmitt, Elia Razzoli, Philipp Aebi

1T-TiSe2 is a quasi-two-dimensional transition metal dichalcogenide, which exhibits a charge density wave transition at a critical temperature of similar to 200 K as well as low-temperature superconductivity induced by pressure or intercalation. The electr ...

Probing two- and three-dimensional electrons in MgB2 with soft x-ray angle-resolved photoemission

Martin Mansson, Thorsten Schmitt

electronic band structure of MgB2 involves a unique combination of two-and three-dimensional (3D) electrons derived from the boron sigma and pi states, respectively. We have mapped out the sigma and pi bands over the complete Brillouin zone, including the ...

Magnons in tetragonal CuO

Henrik Moodysson Rønnow, Frédéric Mila, Marco Grioni, Simon Karl Moser, Thorsten Schmitt, Bastien Dalla Piazza, Sara Fatale, Noore Elahi Shaik

We investigate by resonant inelastic x-ray scattering the magnetic excitations in thin films of tetragonal CuO. We identify a spin wave excitation, dispersing on two cupratelike antiferromagnetic sublattices. Its energy at the boundary of the Brillouin zon ...

Tuning electronic correlations in transition metal pnictides: Chemistry beyond the valence count

Thorsten Schmitt, Joël Mesot, Elia Razzoli, Philipp Aebi

The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the research on iron-based pnictide superconductors. Here we use soft x-ray angle-resol ...

Anisotropic softening of magnetic excitations along the nodal direction in superconducting cuprates

Henrik Moodysson Rønnow, Marco Grioni, Helmuth Berger, Thorsten Schmitt, Marco Guarise, Bastien Dalla Piazza

The high-T-c cuprate superconductors are close to antiferromagnetic order. Recent measurements of magnetic excitations have reported an intriguing similarity to the spin wavesmagnons- of the antiferromagnetic insulating parent compounds, suggesting that ma ...
