The spin states of Co ions in La1.5Ca0.5CoO4 from first-principles
Ting Jia, Hua Wu, Guoren Zhang +4
The spin states and electronic structure of layered perovskite La1.5Ca0.5CoO4 are investigated using fullpotential linearized augmented plane-wave method. All the computational res…
KAgF3: quasi-one-dimensional magnetism in three-dimensional magnetic ions sublattice
Xiaoli Zhang, Guoren Zhang, Ting Jia +3
The electronic structure and magnetic properties of the Jahn-Teller-distorted perovskite KAgF3 have been investigated using the full-potential linerized aug- mented plane-wave meth…
Orbitally relieved magnetic frustration in NaVO2
Ting Jia, Guoren Zhang, Zhi Zeng +1
The magnetic properties of NaVO2 are investigated using full-potential linearized augmented plane wave method. We perform calculations for three structures. For the rhombohedral st…
A dimerized spin fluid in a one-dimensional electron system
Y. Z. Zhang, C. Q. Wu, H. Q. Lin
The ground state of a one-dimensional Hubbard model with a bond-charge attraction W term at half-filling is investigated by the density matrix renormalization group method. It is c…
The Double-Time Green's Function Approach to the Two-Dimensional Heisenberg Antiferromagnet with Broken Bonds
Yun Song, H. Q. Lin, Jue-Lian Shen
We improved the decoupling approximation of the double-time Green's function theory, and applied it to study the spin- two-dimensional antiferromagnetic Heisenberg mode…
