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…
Skyrmion-(Anti)Vortex Coupling in a Chiral Magnet-Superconductor Heterostructure
A. P. Petrović, M. Raju, X. Y. Tee +9
We report experimental coupling of chiral magnetism and superconductivity in [IrFeCoPt]/Nb heterostructures. The stray field of skyrmions with radius ~50nm is sufficient to nucleat…
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…
Coherent and incoherent bands in La and Rh doped Sr3Ir2O7
V. Brouet, L. Serrier-Garcia, A. Louat +6
In Sr2IrO4 and Sr3Ir2O7, correlations, magnetism and spin-orbit coupling compete on similar energy scales, creating a new context to study metal-insulator transitions (MIT). We use…
Formation of an incoherent metallic state in Rh-doped SrIrO
Alex Louat, Fabrice Bert, Lise Serrier-Garcia +4
SrIrO is the archetype of the spin-orbit Mott insulator, but the nature of the metallic states that may emerge from this type of insulator is still not very well known. We…
Time-reversal symmetry breaking hidden order in Sr(Ir,Rh)O
Jaehong Jeong, Yvan Sidis, Alex Louat +2
Layered 5 transition iridium oxides, Sr(Ir,Rh)O, are described as unconventional Mott insulators with strong spin-orbit coupling. The undoped compound, SrIrO, is…
