Exchange Coupling in Eu Monochalcogenides from First Principles
Using a density functional method with explicit account for strong Coulomb repulsion within the 4 f shell, we calculate effective exchange parameters and the corresponding ordering temperatures of the (ferro)magnetic insulating Eu monochalcogenides (EuX; X = O, S, Se, Te) at ambient and elevated pressure conditions. Our results provide quantitative account of the many-fold increase of the Curie...

متن کاملMechanisms of enhanced sulfur tolerance on samarium (Sm)-doped cerium oxide (CeO2) from first principles.
The role of samarium (Sm) 4f states and Sm-perturbed O 2p states in determining the sulfur tolerance of Sm-doped CeO2 was elucidated by using the density functional theory (DFT) + U calculation. We find that the sulfur tolerance of Sm-doped CeO2 is closely related to the modification of O 2p states by the strong interaction between Sm 4f and O 2p states. In particular, the availability of unocc...

Recently, spin selection rules have been invoked to explain the discrepancy between measured and calculated adsorption probabilities of molecular oxygen reacting with Al(111). In this work, we inspect the impact of nonadiabatic spin transitions on the dynamics of this system from first principles. For this purpose the motion on two distinct potential-energy surfaces associated to different spin...
متن کاملFirst-principles LDA+U and GGA+U study of cerium oxides: Dependence on the effective U parameter
The electronic structure and properties of cerium oxides CeO2 and Ce2O3 have been studied in the framework of the LDA+U and GGA PW91 +U implementations of density functional theory. The dependence of selected observables of these materials on the effective U parameter has been investigated in detail. The examined properties include lattice constants, bulk moduli, density of states, and formatio...
