Structural origin of the Jeff=1/2 antiferromagnetic phase in Ga-doped Sr2IrO4
H. W. Wang, L. Y. Zhang, N. Hu +5
Sr2IrO4 hosts a novel Jeff =1/2 Mott state and quasi-two-dimensional antiferromagnetic order, providing a unique avenue of exploring emergent states of matter and functions that ar…
Magnetic and Orbital Order in (MnO)/(MnO) Superlattices Studied via a Double-Exchange Model with Strain
Shuai Dong, Qinfang Zhang, Seiji Yunoki +2
The two-orbital double-exchange model is employed for the study of the magnetic and orbital orders in (MnO)/(MnO) (: rare earths; : alkaline earths)…
Neutron scattering study of magnetic phase separation in nanocrystalline LaCaMnO
Chetan Dhital, Clarina de la Cruz, C. Opeil +5
We demonstrate that magnetic phase separation and competing spin order in the colossal magnetoresistive (CMR) manganites can be directly explored via tuning strain in bulk samples…
Highly anisotropic resistivities in the double-exchange model for strained manganites
Shuai Dong, Seiji Yunoki, Xiaotian Zhang +3
The highly anisotropic resistivities in strained manganites are theoretically studied using the two-orbital double-exchange model. At the nanoscale, the anisotropic double-exchange…

Shuai Dong, Rong Yu, Seiji Yunoki +2
The origin of the spiral spin-order in perovskite multiferroic manganites MnO ( Tb or Dy) is here investigated using a two -orbitals double-exchange model.…
Ferromagnetic tendency at the surface of CE charge-ordered manganites
Shuai Dong, Rong Yu, Seiji Yunoki +2
Most previous investigations have shown that the surface of a ferromagnetic material may have antiferromagnetic tendencies. However, experimentally the opposite effect has been rec…
Dielectrophoresis model for the colossal electroresistance of phase-separated manganites
Shuai Dong, Han Zhu, J. -M. Liu
We propose a dielectrophoresis model for phase-separated manganites. Without increase of the fraction of metallic phase, an insulator-metal transition occurs when a uniform electri…
