Book excerpt: Disordered nature of structural arrangement in amorphous and nanocrystalline alloys gives rise to advantageous soft magnetic properties in particular from a practical application viewpoint [1]. Especially nanocrystalline alloys attract a lot of scienti?c interest because, contrary to their amorphous counterparts, their magnetic parameters do not substantially deteriorate at elevated temperatures during the process of their practical exploitation. To bene?t from their unique magnetic pr- erties, the mechanism of crystallization should be known. Here, we present the study of structural transformation of NANOPERM-type alloys by the help of Mössbauer spectrometry, conventional X-ray diffraction (XRD), and by an advanced diffraction of synchrotron radiation. 2 Experimental Alloys of the composition Fe Mo Cu B for x = 12, 15, 17, 20 prepared by 91?x 8 1 x 57 rapid quenching on a rotating wheel were analyzed in the as-cast state by Fe transmission Mössbauer spectrometry (TMS) and by conversion electron Mössbauer spectrometry (CEMS). The obtained as-quenched ribbons were about 10 mm wide and 20 ?m thick. The nanocrystalline state was achieved by annealing about 2 cm ? long samples for 1 h at temperatures up to 650 C in a vacuum. Conventional XRD was performed with Cu-K radiation in Bragg-Brentano con?guration with graphite ? monochromator in the diffracted beam. Monochromatic synchrotron radiation of 7keV(? = 0. 178 nm) provided at the KMC-2 beamline at BESSY Berlin was used for in situ examinations of structural transformations during continuous heat treatment.

Available in PDF, EPUB and Kindle. Book excerpt: Synthetic hematite aggregates that result from a process that may have industrial and environmental relevance are studied by Mossbauer spectroscopy at room temperature and liquid nitrogen temperature. The Mossbauer results are compared to measurements involving chemical analysis, scanning electron microscopy, and X-ray diffraction on the same samples. Factors such as the crystalline quality of the hematite and the overall sample purity (wt%Fe$\sb2$O$\sb3)$ are followed as functions of the known synthesis conditions. Pure bulk hematite (high quality $\alpha$-Fe$\sb2$O$\sb3$) serves as a reference throughout. Mossbauer spectroscopy is useful in two ways in this problem: (i) it can detect and identify iron-bearing impurities (i.e. non-hematite Fe-compounds), and (ii) it gives much detailed microscopic information on the intra-sample hematite. We find that all of the sulphur seen by chemical analysis probably resides in an iron-bearing compound which, most often, is probably a quenstetite-like material: Fe$\sb2$(SO$\sb4)\sb3\cdot$nH$\sb2$O (n = 9-11). The synthesis conditions are understood to determine both the hematite yield (or sample purity: wt%Fe$\sb2$O$\sb3$) and the intra-hematite crystalline quality, in that these two factors are correlated. Our interpretation of the room temperature Mossbauer spectra resolves coexisting bulk-like and high-defect-density regions whose relative amounts and sample-dependent Mossbauer characteristics can be quantified accurately. On going to liquid nitrogen temperature, a Morin transition is seen to have occurred in all regions of the most bulk-like samples, to have occurred in some regions of intermediate samples, or not to have occurred at all in the samples with the highest defect-density hematites. This illustrates the intricate interplay between microstructural details and cooperative magnetism in hematite materials.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides comprehensive treatment of the current state of glass science from the leading experts in the field. Opening with an enlightening contribution on the history of glass, the volume is then divided into eight parts. The first part covers fundamental properties, from the current understanding of the thermodynamics of the amorphous state, kinetics, and linear and nonlinear optical properties through colors, photosensitivity, and chemical durability. The second part provides dedicated chapters on each individual glass type, covering traditional systems like silicates and other oxide systems, as well as novel hybrid amorphous materials and spin glasses. The third part features detailed descriptions of modern characterization techniques for understanding this complex state of matter. The fourth part covers modeling, from first-principles calculations through molecular dynamics simulations, and statistical modeling. The fifth part presents a range of laboratory and industrial glass processing methods. The remaining parts cover a wide and representative range of applications areas from optics and photonics through environment, energy, architecture, and sensing. Written by the leading international experts in the field, the Springer Handbook of Glass represents an invaluable resource for graduate students through academic and industry researchers working in photonics, optoelectronics, materials science, energy, architecture, and more.
