Electric field-effect on thermodynamics of multiferroic spin chain
Chenglong Jia, Jamal Berakdar
Thermodynamic properties of the helical spins with magnetoelectric coupling is simulated by Monte Carlo algorithm. It is shown that the spin-spin correlations are affected by the t…
Dynamical magnetoelectric effects induced by the Dzyaloshinskii-Moriya interaction in multiferroics
Chenglong Jia, Jamal Berakdar
We study the dynamical interplay between ferroelectricity and magnetism in a multiferroic with a helical magnetic order. We show that the dynamical exchange-striction induces a biq…
A slave-fermion gauge-theory approach of the t-J model: Doping-induced complex magnetic structure and Z spin-gapped anomalous metal in an antiferromagnetic doped Mott insulator
Chenglong Jia, Ki-Seok Kim
We reinvestigate a doped antiferromagnetic Mott insulator based on the slave-fermion approach of the t-J model, where antiferromagnetic spin fluctuations and doped holes are descri…
Spin-polarization coupling in multiferroic transition-metal oxides
Chenglong Jia, Shigeki Onoda, Naoto Nagaosa +1
A systematic microscopic theory of magnetically induced ferroelectricity and lattice modulation is presented for all electron configurations of Mott-insulating transition-metal oxi…
Valence-bond-solid order in antiferromagnets with spin-lattice coupling
Chenglong Jia, Jung Hoon Han
We propose that a valence-bond-solid (VBS) order can be stabilized in certain two-dimensional antiferromagnets due to spin-lattice coupling. In contrast to the VBS state of the Aff…
Lattice-coupled Antiferromagnet on Frustrated Lattices
Chenglong Jia, Jung Hoon Han
Lattice-coupled antiferromagnetic spin model is analyzed for a number of frustrated lattices: triangular, Kagome, and pyrochlore. In triangular and Kagome lattices where ground sta…
