Journal ArticleDOI
Evidence for a low-temperature magnetic ground state in double-perovskite iridates with I r 5 + (5 d 4 ) ions
J. Terzic,Hao Zheng,Feng Ye,Feng Ye,Hengdi Zhao,Pedro Schlottmann,L. E. De Long,Shujuan Yuan,Gang Cao +8 more
TL;DR: In this paper, the authors reported an unusual magnetic ground state in single-crystal, double-perovskite and Sr-doped materials with strong spin-orbit interactions.
Journal ArticleDOI
Electrical Control of Structural and Physical Properties via Strong Spin-Orbit Interactions in Sr 2 IrO 4
TL;DR: A novel coupling between an applied electrical current and the canting angle reduces the Néel temperature and drives a large, nonlinear lattice expansion that closely tracks the magnetization, increases the electron mobility, and precipitates a unique resistive switching effect.
Journal ArticleDOI
Colossal magnetoresistance via avoiding fully polarized magnetization in the ferrimagnetic insulator Mn 3 Si 2 Te 6
TL;DR: In this paper, the authors report colossal magnetoresistance in the stoichiometric Mn3Si2Te6, which is an insulator featuring a ferrimagnetic transition at 78 K.
From J eff = 1 / 2 insulator to p-wave superconductor in single-crystal Sr 2 Ir 1-x Ru x O 4 (0 <= x <= 1)
S.J. Yuan,Saicharan Aswartham,Jasminka Terzic,Hao Zheng,Hengdi Zhao,Pedro Schlottmann,Gang Cao +6 more
TL;DR: In this article, structural, transport, and magnetic properties of Ru doping were investigated and it was shown that substituting $4d\phantom{\rule{0.16em}{0ex}(4{d}^{4})$ ions for $5d\mathrm{I{4}_{1}/acd$ tetragonal structure near $x=0.50$ that accompanies a phase transition from an antiferromagnetic-insulating state to a paramagnetic-metal state.
Journal ArticleDOI
Nonequilibrium orbital transitions via applied electrical current in calcium ruthenates
TL;DR: In this paper, the spin-orbit-coupled antiferromagnet and its derivative with 3% Mn doping to alleviate the violent first-order transition at 357 K were studied and it was shown that small applied electrical current couples to the lattice by significantly reducing its orthorhombic distortions and octahedral rotations.
