,Mechanosynthesis of spinel ferrite nanoparticles followed by M?ssbauer spectroscopy,troscopy. Quantitative information is provided on both ionic and spin configurations in mechanosynthesized spinels. The response of the mechanosynthesized ferrite nanoparticles to changes in temperature is also studied.

,M?ssbauer study of the transition metal phosphorus trichalcogenide FePS3 and spin glass Mn0.5Fe0.5Pl lattice. While these compounds order anti-ferromagnetically at low temperature, the magnetic structures are different. We have reported that these mixtures Mn.Fe.PS. is a spin glass with a glass transition temperature ..=33.7 K. Then, in this work, we report that the results of the temperature var

Synthesis of nanoscale antimony particles,articles which uses an alkoxide-activated sodium hydride as reducing agent of antimony pentachloride. X-ray diffraction and TEM studies confirm the obtaining of amorphous Sb nanoparticles dispersed in an organic matrix. .Sb M?ssbauer spectroscopy gives evidence for the occurrence of interactions bet

Chemical reduction of hematite by sodium borohydride,y magnetic black powder, which is stable at RT. The NaBH. treatment converts about half of the hematite to an amorphous Fe-B alloy and to a small fraction of sub-micron sized, amorphous metallic-Fe nodules. Heating at 400°C of this composite has resulted in the crystallization and/or oxidation of mo

The effect of the sputtering process ambient on the magnetic state and phase composition of the filate and phase composition has been investigated. It was shown that the presence of oxygen resulted in the formation of oxide shells preventing the ferromagnetic interaction between Co.Fe.Zr. nanoparticles and also the formation of metallic percolative net beyond the percolation threshold (as opposed

,M?ssbauer studies of phosphate glasses for the immobilisation of toxic and nuclear wastes,d largely occupied sites with distorted octahedral coordination for both redox states. Using a base glass of nominal composition 60 P.O.-40 Fe.O. (mol%), stepwise molar replacement of Fe.O. by (0.67 Na.O×0.33 Al.O.) increased the redox ratio, Fe./ΣFe, from 0.13 at 40% Fe.O. to 0.25 at 10% Fe.O.. The
