Magnetic Ordering in Gd Monopnictides: Indirect Exchange Versus Superexchange Interaction

Study of Magnetic Superexchange in diluted Systems

model the covalency-mixing parameters, λσ and λπ, the electron spin transfer coefficients, ƒi (i=σ, π, s ), and the total charge, C, transferred from ligand to the chromium ions, are evaluated. The variation of bσσ and bσπ with x agree with the passage of the system from ferromagnetic to antiferromagnetic order. For the compound presenting re-entrant behaviour ( 58 . 0 45 . 0 ≤ ≤ x ), fs exhibi...

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Superexchange-driven magnetoelectricity in magnetic vortices.

We demonstrate that magnetic vortices in which spins are coupled to polar lattice distortions via superexchange exhibit an unusually large linear magnetoelectric response. We show that the periodic arrays of vortices formed by frustrated spins on kagome lattices provide a realization of this concept; our ab initio calculations for such a model structure yield a magnetoelectric coefficient that ...

Frontier Hybrid Orbitals . II . Applications

In this paper, the frontier hybrid orbitals (FBO's) of a series of octahedral ML5 fragments are used to discuss the electronic structure and the chemical bond of these fragments and the molecules built of these ML5 fragments. The bond orbitals which are chosen as the linear combination of the frontier hybrid orbitals . of fragments are calculated and explain the electronic structure and propert...
