Phase separation and ferroelectric ordering in charge frustrated LuFe2O4-x
H. X. Yang, H. F. Tian, Y. Zhang +6
The transmission electron microscopy observations of the charge ordering (CO) which governs the electronic polarization in LuFe2O4-x clearly show the presence of a remarkable phase…
First principles perspective on the microscopic model for Cs2CuCl4 and Cs2CuBr4
K. Foyevtsova, Y. Zhang, H. O. Jeschke +1
We investigate the microscopic model for the frustrated layered antiferromagnets Cs2CuCl4 and Cs2CuBr4 by performing ab initio density functional theory (DFT) calculations and with…
O- and H- induced surface core level shifts on Ru(0001): Prevalence of the additivity rule
S. Lizzit, Y. Zhang, K. L. Kostov +4
In previous work on adsorbate-induced surface core level shifts (SCLSs), the effects caused by O atom adsorption on Rh(111) and Ru(0001) were found to be additive: the measured shi…
Proximity of LaOFeAs to a magnetic instability
I. Opahle, H. C. Kandpal, Y. Zhang +2
We investigate the effect of external pressure on the Fe magnetic moment in undoped LaOFeAs within the framework of density functional theory and show that this system is close to…
Nonlinear current-voltage behavior and electrically driven phase transition in charge frustrated LuFe2O4
L. J. Zeng, H. X. Yang, Y. Zhang +5
Electric transport measurements of the charge frustrated LuFe2O4, in which the charge ordering (CO) and electronic ferroelectricity are found, reveal strong nonlinear electric cond…
Multi-ferroelectricity in charge ordered LuFe2O4(LuFeO3)n with n=1
H. X. Yang, Y. Zhang, C. Ma +4
Electronic ferroelectricity from charge ordering (CO) is currently a significant issue that has been extensively investigated in the charge/spin frustrated LuFe2O4 system. Chemical…
