Photoemission Evidence of a Novel Charge Order in Kagome Metal FeGe
Zhisheng Zhao, Tongrui Li, Peng Li +16
A charge order has been discovered to emerge deep into the antiferromagnetic phase of the kagome metal FeGe. To study its origin, the evolution of the low-lying electronic structur…
Spectral signatures of a unique charge density wave in TaNiSe
Matthew D. Watson, Alex Louat, Cephise Cacho +4
Charge Density Waves (CDW) are commonly associated with the presence of near-Fermi level states which are separated from others, or "nested", by a wavector of . Here we…
Origin of the different electronic structure of Rh- and Ru-doped Sr2IrO4
Véronique Brouet, Paul Foulquier, Alex Louat +4
One way to induce insulator to metal transitions in the spin-orbit Mott insulator Sr2IrO4 is to substitute iridium with transition metals (Ru, Rh). However, this creates intriguing…
Optical Signature of a Crossover from Mott- to Slater-type Gap in SrIrRhO
B. Xu, P. Marsik, E. Sheveleva +5
With optical spectroscopy we provide evidence that the insulator-metal transition in SrIrRhO occurs close to a crossover from the Mott- to the Slater-type.…
ARPES study of orbital characters, symmetry breakings and pseudogaps in doped and pure Sr2IrO4
Alex Louat, Benjamin Lenz, Silke Biermann +6
Sr2IrO4 is characterized by a large spin-orbit coupling, which gives rise to bands with strongly entangled spin and orbital characters, called J=1/2 and J=3/2. We use light-polariz…
Magnetization density distribution of SrIrO: Deviation from a local picture
Jaehong Jeong, Benjamin Lenz, Arsen Gukasov +10
iridium oxides are of huge interest due to the potential for new quantum states driven by strong spin-orbit coupling. The strontium iridate SrIrO is particularly in th…
