Incommensurate Magnetic Order in the Kagome Metal GdVSn
Zach Porter, Ganesh Pokharel, Jong-Woo Kim +2
We characterize the magnetic ground state of the topological kagome metal GdVSn via resonant X-ray diffraction. Previous magnetoentropic studies of GdVSn suggested…
Quasi-2D anomalous Hall Mott insulator of topologically engineered Jeff =1/2 electrons
Junyi Yang, Hidemaro Suwa, Derek Meyers +12
We investigate an experimental toy-model system of a pseudospin-half square-lattice Hubbard Hamiltonian in [(SrIrO3)1/(CaTiO3)1] to include both nontrivial complex hopping and mode…
Controllable emergent spatial spin modulation in Sr2IrO4 by in situ shear strain
S. Pandey, H. Zhang, J. Yang +8
Symmetric anisotropic interaction can be ferromagnetic and antiferromagnetic at the same time but for different crystallographic axes. We show that inducing competition of anisotro…
Hole doping in a negative charge transfer insulator
Ranjan Kumar Patel, Krishnendu Patra, Shashank Kumar Ojha +7
NiO is a negative charge transfer energy system and exhibits a temperature-driven metal-insulator transition (MIT), which is also accompanied by a bond disproportionation (…
A magnetic Weyl semimetallic phase in thin films of EuIrO
Xiaoran Liu, Shiang Fang, Yixing Fu +17
The interplay between electronic interactions and strong spin-orbit coupling is expected to create a plethora of fascinating correlated topological states of quantum matter. Of par…
Optical magnons with dominant bond-directional exchange interactions in a honeycomb lattice iridate -LiIrO
Sae Hwan Chun, P. Peter Stavropoulos, Hae-Young Kee +6
We have used resonant inelastic x-ray scattering to reveal optical magnons in a honeycomb lattice iridate -LiIrO. The spectrum in the energy region 20-25 meV exhibit…
Strain-modulated Slater-Mott crossover of pseudospin-half square-lattice in (SrIrO3)1/ (SrTiO3)1 superlattices
Junyi Yang, Lin Hao, Derek Meyers +15
We report on the epitaxial strain-driven electronic and antiferromagnetic modulations of a pseudospin-half square lattice realized in superlattices of (SrIrO3)1/(SrTiO3)1. With inc…
Anomalous Magnetoresistance due to Longitudinal Spin Fluctuations in a Jeff = 1/2 Mott Semiconductor
Lin Hao, Zhentao Wang, Junyi Yang +12
As a hallmark of electronic correlation, spin-charge interplay underlies many emergent phenomena in doped Mott insulators, such as high-temperature superconductivity, whereas the h…
Giant magnetic response of a two-dimensional antiferromagnet
Lin Hao, D. Meyers, Hidemaro Suwa +14
A fundamental difference between antiferromagnets and ferromagnets is the lack of linear coupling to a uniform magnetic field due to the staggered order parameter. Such coupling is…
Magnetism in artificial Ruddlesden-Popper iridates leveraged by structural distortions
D. Meyers, Yue Cao, G. Fabbris +18
We report on the tuning of magnetic interactions in superlattices composed of single and bilayer SrIrO inter-spaced with SrTiO. Magnetic scattering shows predominately -…

We report an experimental investigation of the two-dimensional = 1/2 antiferromagnetic Mott insulator by varying the interlayer exchange coupling in [(SrIrO)$_1…
Atomic-scale control of magnetic anisotropy via novel spin-orbit coupling effect in La2/3Sr1/3MnO3/SrIrO3 superlattices
Di Yi, Jian Liu, Shang-Lin Hsu +11
Magnetic anisotropy (MA) is one of the most important material properties for modern spintronic devices. Conventional manipulation of the intrinsic MA, i.e. magnetocrystalline anis…
