Enhanced Magnetization and Conductivity in NiFe2O4
Ching Cheng
Different configurations of magnetic orders and cation distributions for NiFe2O4 are studied by the density functional based methods with the possible inclusion of the on-site Coul…
Atomic and magnetic structures of (CuCl)LaNbO and (CuBr)LaNbO: Density functional calculations
Chung-Yuan Ren, Ching Cheng
The atomic and magnetic structures of (Cu)LaNbO (=Cl and Br) are investigated using the density-functional calculations. Among several dozens of examined structures,…
Magnetism in 2D BNO and BSiN: polarized itinerant and local electrons
Ru-Fen Liu, Ching Cheng
We use density functional theory based first-principles methods to study the magnetism in a 2D hexagonal BN sheet induced by the different concentrations of oxygen and silicon atom…
Long-range antiferromagnetic interactions in ZnFe2O4 and CdFe2O4
Ching Cheng
For the first time, the Fe-Fe interactions in the geometrically frustrated antiferromagnetic systems of zinc and cadmium ferrites are determined quantitatively by the first-princip…
Ab initio Studies of the Possible Magnetism in BN Sheet by Non-magnetic Impurities and Vacancies
Ru-Fen Liu, Ching Cheng
We performed first-principles calculations to investigate the possible magnetism induced by the different concentrations of non-magnetic impurities and vacancies in BN sheet. The a…
A structural path for the icosahedra <-> fcc structural transition in clusters
Ching-Ming Wei, Ching Cheng, Chun-Ming Chang
We propose a structural path for the icosahedra <-> fcc transition in clusters and demonstrate the transition in Pb_13 by ab initio molecular-dynamics simulation. The proposed path…
