Correlated Quantum Phenomena of Spin-Orbit Coupled Perovskite Oxide Heterostructures: Cases of SrRuO3 and SrIrO3-Based Artificial Superlattices
Seung Gyo Jeong, Jin Young Oh, Lin Hao +2
Unexpected, yet useful functionalities emerge when two or more materials merge coherently. Artificial oxide superlattices realize atomic and crystal structures that are not availab…
Extraordinary magnetic response of an anisotropic 2D antiferromagnet via site-dilution
Junyi Yang, Hidemaro Suwa, Derek. Meyers +9
A prominent character of two-dimensional magnetic systems is the enhanced spin fluctuations, which however reduce the ordering temperature. Here we report that a magnetic field of…
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…
Manipulate the Electronic State of Mott Iridate Superlattice through Protonation Induced Electron-Filling
Meng Wang, Lin Hao, Fang Yin +12
Spin-orbit-coupled Mott iridates show great similarity with parent compounds of superconducting cuprates, attracting extensive research interests especially for their electron-dope…
Anomalous Magnetoresistance by Breaking Ice Rule in Bi2Ir2O7/Dy2Ti2O7 Heterostructure
H. Zhang, C. K. Xing, K. Noordhoek +14
While geometrically frustrated quantum magnets are known for a variety of exotic spin states that are of great interests of understanding emergent phenomena as well as enabling rev…
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 in Centrosymmetric Skyrmion-Lattice Magnet Gd2PdSi3
Han Zhang, Qing Huang, Lin Hao +5
We performed a systematic study of the temperature- and field-dependence of magnetization and resistivity of Gd2PdSi3, which is a centrosymmetric skyrmion crystal. While the magnet…
Comprehensive Control of Metamagnetic Transition of Antiferromagnetic Mott Insulator Sr2IrO4 by in-situ Anisotropic Strain
H. Zhang, L. Hao, J. Yang +10
Metamagnetism in antiferromagnets exhibits distinct critical behaviors and dynamics when invoking spin reversal and rotation. Here we show a 0.05% anisotropic strain suffices to in…
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…
Epitaxial stabilization of Sr3Ir2O7 thin films
Junyi Yang, Lin Hao, Peyton Nanney +8
Ruddlesden-popper type Srn+1IrnO3n+1 compound is a major focus of condensed matter physics where the subtle balance between electron-electron correlation, spin-orbit interaction an…
Decoupling carrier concentration and electron-phonon coupling in oxide heterostructures observed with resonant inelastic x-ray scattering
D. Meyers, Ken Nakatsukasa, Sai Mu +19
We report the observation of multiple phonon satellite features in ultra thin superlattices of form SrIrO/SrTiO using resonant inelastic x-ray scattering. As the valu…
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…
Novel spin-orbit coupling driven emergent states in iridate-based heterostructures
Lin Hao, D. Meyers, M. P. M. Dean +1
Recent years have seen many examples of how the strong spin-orbit coupling (SOC) present in iridates can stabilize new emergent states that are difficult or impossible to realize i…
