Ab Initio Study of the Intrinsic Exchange Bias at the SrRuO/SrMnO Interface
Shuai Dong, Qinfang Zhang, Seiji Yunoki +2
In a recent publication (S. Dong et al., Phys. Rev. Lett.103, 127201 (2009)), two (related) mechanisms were proposed to understand the intrinsic exchange bias present in oxides het…
Microscopic model for the ferroelectric field effect in oxide heterostructures
Shuai Dong, Xiaotian Zhang, Rong Yu +2
A microscopic model Hamiltonian for the ferroelectric field effect is introduced for the study of oxide heterostructures with ferroelectric components. The long-range Coulomb inter…
Asymmetric magnetization splitting in diamond domain structure: Dependence on exchange interaction and anisotropy
Kaixuan Xie, Xiaopu Zhang, Weiwei Lin +2
The distributions of magnetization orientation for both Landau and diamond domain structures in nano-rectangles have been investigated by micromagnetic simulation with various exch…
Computational Design of Axion Insulators Based on 5d Spinels Compounds
Xiangang Wan, Ashvin Vishwanath, Sergey Y. Savrasov
Based on density functional calculation with LDA+U method, we propose that hypothetical Osmium compounds such as CaOs2O4 and SrOs2O4 can be stabilized in the geometrically frustrat…
Manipulating the fully spin-polarized edge currents in graphene ribbon
Lei Xu, Jin An, Chang-De Gong
Electron fully spin-polarized edge states in graphene emerged at the interfaces of a nonuniform magnetic field are studied numerically in a tight-binding model, with both the orbit…
Electric and Magnetic Excitation of Coherent Magnetic Plasmon Waves in a One-dimensional Meta-chain
C. Zhu, H. Liu, S. M. Wang +7
A one-dimensional diatomic meta-chain with equal-size holes and different-length slits is designed. Broadband coherent magnetic plasmon waves (MPW) are formed in such a system, exc…
