Available in PDF, EPUB and Kindle. Book excerpt: Amorphous oxides which are transparent and conducting find use in display devices and as top electrodes in energy applications, while those which are conducting and magnetic have the potential to be used in spintronics. With the fast approaching limit of Moore’s law, new materials are needed where the spin and polarization of the electrons are coupled. Despite progress in transparent conductors, materials selection is limited by the need to have wide optical bandgap and conduction via s-orbital. In contrast, search for new spintronics materials has picked up only in the last decade. Here we report the synthesis, characterization, and application of a new oxide made from Fe, Tb, and Dy - elements that do not conduct via the s-orbital. Thin films (100 nm) of this oxide were synthesized by pulsed laser deposition (PLD) as a function of varying oxygen pressure, and by electron-beam evaporation as a function of the cation composition, and then annealed under different conditions. Films deposited at 5x10-8 Torr exhibited high optical transparency (90%) and conductivity (~104 S/m). Films deposited at O2 pressures below 1x10-5 Torr were conductive (~104 S/m), magnetic (up to 480 emu/cc), and optically transparent, while the ones above 1x10-5 Torr were optically transparent but insulating and non-magnetic. Changes in the cation stoichiometry showed the films’ transition from being metallic to semiconducting with decreasing Fe content relative to the Lanthanides. However, when a very iron-rich film was annealed through several heating and cooling cycles in low vacuum, the film evolved into a semiconductor that was stable in ambient conditions and showed very high conductivity (2.8x105 S/m) and room temperature magnetism (380 emu/cc). The PLD deposited films were utilized as the ferromagnetic layer for magneto-electric coupling with bismuth ferrite as well as a top electrode for bismuth ferrite capacitors. A giant magneto-resistance (GMR) device made from the Fe-Tb-Dy-oxide and bismuth ferrite showed evidence of magneto-electric coupling at room temperature. The discovery of this oxide not only introduces new materials physics that could be explored and exploited to engineer new multifunctional materials, but the oxide itself proves to be very promising for spintronics device applications.

Available in PDF, EPUB and Kindle. Book excerpt: In order to use rare earths successfully in various applications, a good understanding of the chemistry of these elements is of paramount importance. Nearly three to four decades have passed since titles such as The Rare Earths edited by F.H. Spedding and A.H. Daane, The chemistry of the Rare Earth Elements by N.E. Topp and Complexes of the Rare Earths by S.P. Sinha were published. There have been many international conferences and symposia on rare earths, as well as the series of volumes entitled Handbook of Physics and Chemistry of Rare Earths edited by K.A. Gschneidner and L. Eyring. Thus, there is a need for a new title covering modern aspects of rare earth complexes along with the applications. The present title consists of twelve chapters. 1. Introduction2. General aspects3. Stability of complexes4. Lanthanide complexes5. Structural chemistry of lanthanide compounds6. Organometallic complexes7. Kinetics and mechanisms of rare earths complexation8. Spectroscopy of lanthanide complexes9. Photoelectron spectroscopy of rare earths10. Lanthanide NMR shift reagents11. Environmental ecological biological aspects12. Applications The authors studied in schools headed by pioneers in rare earth chemistry, have a combined experience of one hundred and fifty years in inorganic chemistry, rare earth complex chemistry, nuclear and radiochemistry of rare earths and supramolecular chemistry. The present monograph is a product of this rich experience.

Book excerpt: This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.

Available in PDF, EPUB and Kindle. Book excerpt: Crystals are sometimes called 'Flowers of the Mineral Kingdom'. In addition to their great beauty, crystals and other textured materials are enormously useful in electronics, optics, acoustics and many other engineering applications. This richly illustrated text describes the underlying principles of crystal physics and chemistry, covering a wide range of topics and illustrating numerous applications in many fields of engineering using the most important materials today. Tensors, matrices, symmetry and structure-property relationships form the main subjects of the book. While tensors and matrices provide the mathematical framework for understanding anisotropy, on which the physical and chemical properties of crystals and textured materials often depend, atomistic arguments are also needed to quantify the property coefficients in various directions. The atomistic arguments are partly based on symmetry and partly on the basic physics and chemistry of materials. After introducing the point groups appropriate for single crystals, textured materials and ordered magnetic structures, the directional properties of many different materials are described: linear and nonlinear elasticity, piezoelectricity and electrostriction, magnetic phenomena, diffusion and other transport properties, and both primary and secondary ferroic behavior. With crystal optics (its roots in classical mineralogy) having become an important component of the information age, nonlinear optics is described along with the piexo-optics, magneto-optics, and analogous linear and nonlinear acoustic wave phenomena. Enantiomorphism, optical activity, and chemical anisotropy are discussed in the final chapters of the book.
