Journal ArticleDOI
Band-Structure Trend in Hole-Doped Cuprates and Correlation with T c max
TL;DR: By calculation and analysis of the bare conduction bands in a large number of hole-doped high-temperature superconductors, the range of the intralayer hopping is identified as the essential, material-dependent parameter.
Journal ArticleDOI
Electronic Structure of Sr 2 FeMoO 6
TL;DR: In this paper, the unusual electronic structure of 2FeMoO 6 was analyzed by combining ab initio and model Hamiltonian approaches, and the results indicated that there are strong enhancements of the intra-atomic exchange strength at the Mo site as well as the antiferromagnetic coupling strength between Fe and Mo sites.
Journal ArticleDOI
Muffin-tin orbitals of arbitrary order
TL;DR: In this article, the authors derived orbital basis sets from scattering theory and expressed them as polynomial approximations to the energy dependence of a set of partial waves, in quantized form.
Journal ArticleDOI
Electronic structure, phonons, and dielectric anomaly in ferromagnetic insulating double pervoskite La2NiMnO6.
TL;DR: This study reveals the existence of very soft infrared active phonons that couple strongly with spins at the Ni and Mn sites through modification of the superexchange interaction, and suggests that these modes are the origin for the observed dielectric anomaly in La2NiMnO6.
Journal ArticleDOI
Structure, bonding, and magnetism of cobalt clusters from first-principles calculations
Soumendu Datta,Mukul Kabir,Shreemoyee Ganguly,Biplab Sanyal,Tanusri Saha-Dasgupta,Abhijit Mookerjee +5 more
TL;DR: The structural, electronic, and magnetic properties of cobalt clusters have been investigated using density functional theory within the pseudopotential plane wave method as discussed by the authors, where the average coordination number is found to dominate over the average bond length to determine the effective hybridization and consequently the cluster magnetic moment.
