Synthesis and magnetic properties of Cu0.5Ni0.5Fe2O4 nanoparticles produced by glycothermal and hyder gauge pressure of 100?psi. The hydrothermal treatment was done at 100°C under zero pressure. Complete single-phase cubic spinel structure in the samples made by glycothermal (sample G) and hydrothermal (sample H) processes formed after annealing at 600°C and 900°C respectively. The coercive field

Magnetic phase transitions in nanoclusters and nanostructures,nostructures in the beginning of sintering, (3) nanostructures induced by shear stress under high-pressure action, (4) ordered iron oxide nanostructures. The thermodynamic models for FOMPT appearance and cluster critical size are proposed. The role of surface tension, defect density and nanocluster organization are discussed.

Adherent

Characterization of magnetic iron oxide nanoparticles, is to synthezise and characterize ε-Fe.O. magnetic nanoparticles embedded in amorphous SiO. matrix. The M?ssbauer spectroscopy analysis of the samples was complemented by the study of X-ray powder diffraction and high-resolution transmission electron microscopy.

玩忽職守

,Hydrogenation of FeCoZr–Al2O3 nanocomposites studied by M?ssbauer spectroscopy and magnetometry,scopy and magnetometry. Variations of local structure, blocking temperature and mean FeCoZr nanoparticles’ volume are discussed with respect to (i) composition and (ii) two competing processes—H. incorporation and annealing—occurred during treatment in H. plasma.

Assault

,M?ssbauer study of rapidly solidified Al-Fe based amorphous alloys,on diminishes the glass forming ability and results in precipitation of the stable AlSb compound. The X-ray amorphous Al.Fe.Y. alloy shows a short range order resembling to the Al.Fe compound as it can be judged from the M?ssbauer data.

,Integral low-energy electron M?ssbauer spectroscopic studies of the surfaces of carbon nanotube-nanS). Several samples, prepared by reduction of .-(Al,Fe).O. or (Mg,Fe)Al.O. precursors in a H.-CH. atmosphere, were investigated, demonstrating that ILEEMS is a promising tool completing transmission M?ssbauer spectroscopy for the investigation of the metal Fe and iron-carbide particles in the different carbon nanotube systems.
