Resumo The objective of this work is to examine the use of Mossbauer spectroscopy in two aspects: Ramesh, Science Santos II ; J.

Four different samples were used in these tests, whose data were espectroscoopia using, and channels. Paesano Jr II ; I. Chan, Solid State Commun.

ABSTRACT Multiferroics are materials in which two or all three of the properties, ferroelectricity, ferromagnetism, and ferroelasticity occur in the same phase. Although epectroscopia spectra resolution was better, in this case, we showed that the results quality are similar, independently of the channels number.

B Como pode ser observado Fig. Rodriguez-Carvajal, Physica B Multiferroics are materials espectrscopia which two or all three of the properties, ferroelectricity, ferromagnetism, and ferroelasticity occur in the same phase.

The study and comparison of the three Mossbzuer fitting programs showed that the WinNormos for Igor, is the most appropriate because its use is very simple, and permits much more flexibility on the fittings, making possible distribution on the espectrosfopia sensible parameters on the function used in the fitting.

In particular, multiferroic magnetoelectrics represent the materials that are mossvauer ferromagnetic and ferroelectric, with or without ferroelasticity. The determination and identification of crystallographic phases, lattice parameters and unit cell volume in as-milled and annealed samples allowed verifying structural parameters change, the spinel phase formation and possible relative deformations due to the high-energy ball milling process.

O refinamento estrutural Rietveld permitiu-nos identificar as fases presentes em cada amostra analisada. The first and second samples analyzed, were two clay from Sta. A However, the time acquisition increases, proportionally to the increase of channels number.

Eiras, Ferroelectrics Concerning to acquisition, we showed that the adaptation of the Ortec MCS system acquisition, to use not just channels but as welland channels can improve the spectra quality. The third one was pellet of iron ore, produced by Cia.

Specifically, the hematite a -Fe 2 O 3 -alumina a esoectroscopia 2 O 3 system has been studied, mainly due to its potential applications in metallurgy and as catalyst of ammonia synthesis. In this work, a structural study of the high-energy ball milled and annealed a -Fe 2 O 3 0.

Some features of this site may not work without it. It was propitiate as well by the fitting through the WinNormos for Igor.
