La1.5Sr0.5CoMn0.5Fe0.5O6 (LSCMFO) compound was prepared by solid state reaction and its structural, electronic magnetic properties were investigated. The material forms in rhombohedral [Formula: see text] structure, the presence of distinct interactions leads to formation a Griffiths phase above FM transition temperature (150 K), possibly related nucleation small short-ranged ferromagnetic clusters. At low temperatures, spin glass-like emerges system exhibits both conventional spontaneous...
We present here an experimental and theoretical study of the Ti-ferrite (TiFe2O4, ülvospinel). The was performed in framework density functional theory using full-potential linearized augmented plane waves method employing different approximations for exchange correlation potential. In order to discuss magnetic ordering electronic structure system, we considered distributions Fe/Ti atoms two cationic sites and, each distribution, spin arrangements (ferromagnetic, ferrimagnetic...
We present a numerical study of the magnetic properties ZnFe2O4 using Monte-Carlo simulations performed considering Heisenberg model with antiferromagnetic couplings determined by Density Functional Theory. Our calculations predict that susceptibility has cusp-like peak centered at 13 K, and follows Curie-Weiss behavior above this temperature high negative ( ΘCW=-170 K). These results agree experimental data once extrinsic contributions give rise to deviation from law are discounted....

Laser ablation gives a appropiate method for processing of wide variety solids materials. graphite target has proved to be the most appropriated novel materials preparation carbon compounds like fullerenes, single wall nanotubes, and thin films diamond (DLC) so on. However, production high quality with unique characteristic, is desirable know composition particles energies that are deposited understand mechanics produce these particles. We use Optical Emission spectroscopy obtain information...
We present a Density Functional Theory (DFT) based study of the structural and magnetic properties (001) surface semiconducting oxide ZnFe2O4 (spinel structure). The calculations were performed using DFT ab initio plane wave pseudopotential method as implemented in Quantum Espresso code. all electron Full-potential linearized-augmented-plane-wave (FP-LAPW) was also employed to check accuracy method. In both DFT+U methodology different terminations studied: find that terminated Zn is stable...
