Electronic Structure and Magnetic Interactions in Ti Based on first-principles calculation method, the electronic structure and magnetic interactions of Ti-doped -Ga 2 O 3 and Ti-V O-co-doped in -Ga 2 O 3 have been investigated. The calculated results indicate that Ti atom tends to substitute the Ga atom at the octahedral coordinated site and the doped system prefers spin-polarized state.

Single-molecule magnets V15 (K6[V15As6O42(H2O)]8H2O) have attracted a great deal of attention recently. These magnets are promising systems for studying such fundamental problems as spin tunneling, spin coherence, and low-temperature spin relaxation. To understand in detail the internal magnetic and electronic structure, and the intramolecular interactions responsible for the
Electronic structure and exchange interactions in the of electron states and magnetic exchange interactions in the pyrochlores. Our analysis is based on results of density-functional studies of the electronic structure and on results of simple models that we develop for the magnetic exchange. We propose that the relatively weak ferromagnetism in the
Electronic structure and magnetic exchange coupling in Density-functional studies of the electronic structures and exchange interaction parameters have been performed for a series of ferromagnetic full Heusler alloys of general formula Co 2 MnZ (Z=Ga,Si,Ge,Sn) , Rh 2 MnZ (Z=Ge,Sn,Pb) , Ni 2 MnSn , Cu 2 MnSn , and Pd 2 MnSn , and the connection between the electronic spectra and the magnetic interactions have been studied. Different mechanisms
This different electronic behaviour is responsible for the robust insulating state of CrBr 3, in which the magnetic exchange constants evolve monotonically with pressure, and the proximity to a metalinsulator transition predicted for Cr 2 Ge 2 Te 6, which causes a non-monotonic evolution of its magnetic ordering temperature. We provide a microscopic understanding for the pressure evolution of the magnetic
Electronic structure and magnetic interactions in MnN and Electronic structure calculations were performed for MnN and Mn3N2 using a full-potential linearized muffin-tin orbital method in the local spin density approximation. Structural relaxation by ener
Electronic structure and magnetic interactions in Ni-doped Sep 01, 2009 · Based on first-principles spin-polarized density functional theory calculations, the electronic structures and magnetic interactions of Ni-doped -Ga 2 O 3 are investigated. Calculations predict that the spin-polarized state, with a magnetic moment of about 1.0 or 3.0 B per Ni-dopant when one Ni atom substitutes the octahedral or tetrahedral site, is more favorable in energy than that of non
