Journal ArticleDOI
Novel Jeff=1/2 Mott state induced by relativistic spin-orbit coupling in Sr2IrO4.
B. J. Kim,Hosub Jin,S. J. Moon,J.-Y. Kim,Byeong-Gyu Park,Choon Shik Leem,Jaejun Yu,Tae-Hee Noh,Chang Sook Kim,Se-Jung Oh,Jae-Hoon Park,V. Durairaj,Gang Cao,Eli Rotenberg +13 more
TL;DR: The electronic structure of 5d transition-metal oxide Sr2IrO4 is investigated using angle-resolved photoemission, optical conductivity, x-ray absorption measurements, and first-principles band calculations, suggesting a new class of Jeff quantum spin driven correlated-electron phenomena.
Journal ArticleDOI
Thermal, magnetic, and transport properties of single-crystal Sr 1 − x Ca x RuO 3 ( 0 x 1 . 0 )
TL;DR: In this article, as-grown, untwinned, orthorhombic single-crystal samples of Ru-O oxides were used for the Hall effect measurement.
Journal ArticleDOI
Dimensionality-controlled insulator-metal transition and correlated metallic state in 5d transition metal oxides Sr n+1Ir nO3n+1 (n=1, 2, and infinity)
S. J. Moon,Hosub Jin,Kyung Wan Kim,Wonshik Choi,Yun Sang Lee,Jong-Sung Yu,Gang Cao,A. Sumi,Hiroshi Funakubo,Christian Bernhard,Tae-Hee Noh +10 more
TL;DR: The artificially synthesized perovskite SrIrO3 showed a very large mass enhancement of about 6, indicating that it was in a correlated metallic state, and a Mott insulator-metal transition with a change of bandwidth as the authors increased n.
Journal ArticleDOI
Tuning electronic structures via epitaxial strain in Sr2IrO4 thin films
John Nichols,J. Terzic,E. G. Bittle,O. B. Korneta,L. E. De Long,Joseph W. Brill,Gang Cao,Sung Seok A. Seo +7 more
TL;DR: In this paper, the electronic structures of epitaxial Sr2IrO4 thin-films were studied as a function of lattice-strains and it was shown that the electronic correlation energy is also affected by in-plane latticestrains.
Journal ArticleDOI
Weak ferromagnetism, metal-to-nonmetal transition, and negative differential resistivity in single-crystal Sr 2 IrO 4
TL;DR: In this article, the effect of magnetic susceptibility and isothermal magnetization on single-crystal ruthenates has been investigated and it was shown that there is no correlation between conductivity and magnetism.
