Available in PDF, EPUB and Kindle. Book excerpt: After the theoretical prediction of Dietl in 2000 in Science magazine for a possibility to make many semiconductors become high temperature ferromagnetic, there has been a strong wave of research arisen in numerous laboratories of physics and chemistry all over the world following this direction, with hope to find materials that are really useful for spintronics applications. If we can experimentally obtain such amazing compounds, certainly they must be very promising candidates for future technologies. Besides traditional types of semiconductors such as GaAs or GaN, etc, many oxides such as ZnO, TiO2, SnO2 or In2O3 have attracted a lot of attentions of researchers in the field of materials, due to their diversities in characteristics, so that they are interesting and challenging as well. Over the last few years, issues on magnetism of diluted magnetic semiconductors (lately also the research has been stretched further to diluted magnetic insulators as well), have become ones of the most interesting and questionable focuses in magnetism and science of the century. Since the subject is fashionable, in one side it is exciting for us, physicists and chemists, to deal with, but in the other side, it is hard because there are always a lot of competitions, and besides the compliments, a lot of criticisms that come along as well. Therefore, working on this field makes our everyday basis of research become very challenging, and inspirational, like we have a debate to surpass ourselves. In this book I would like to present to the readers a modest collection of review articles on magnetism of special types of semiconducting and insulating oxides written by outstanding scientists, who are ones of key players in the field of diluted magnetic semiconductors at the moment. The articles will cover from the theoretical models to the on-going experimental results. I hope that this book will bring you an overall view about the very up-to-date status of this new research field, as well as a fresh inspiration that we want to share with all our colleagues worldwide. One can see that many doors are still opened and plenty of things are waiting for us to explore altogether.

Available in PDF, EPUB and Kindle. Book excerpt: The nascent field of spintronics requires materials that exhibit room-temperature ferromagnetism while retaining their semiconducting properties. A clever strategy for creating these materials is by substituting magnetic transition metals onto the cation sites of commonly used binary semiconductors in order to incorporate magnetic property (e.g. Mn-substituted GaAs). A materials system of great interest is transition-metal substituted ZnO, which was predicted by Dietl and co-workers [1] to be a room temperature ferromagnet with manganese substitution and hole doping. Despite a great deal of effort in preparing thin films of transition-metal substituted ZnO, there has not been reproducible evidence of ferromagnetism in this system; Curie temperatures and magnetic moments vary significantly between studies. In our work, bulk transition metal substituted ZnO samples were prepared and characterized in order to accurately determine their properties. We find no evidence for ferromagnetic behavior in either the Zn1-xCo xO nor the Zn1-xMn xO systems; rather the dominant nearest-neighbor interactions are antiferromagnetic. A similar behavior is observed in nanoparticulate analogs of the bulk materials. Along with substituted ZnO, the 'end-member' of the Zn1-xCox O system, novel wurzite CoO was also prepared and studied. Finally, solid solutions of a dilute ferrimagnetic semiconductor system, iron-substituted ZnGa2O4, were prepared and found to possess long-range magnetic ordering ferromagnetic hysteresis at low temperatures. Optical spectroscopy indicates that the iron substitution does not greatly alter the position of the band edge, hence maintaining the semiconducting properties. Such promising results suggest that dilute ferrimagnetic semiconductors, which do not require conduction electrons to induce magnetism, are worthy of further investigation.

This book was released on 2014-07-23 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spintronics, short notation for spin-based electronics, is a research area which seeks to exploit the spin of electrons in addition to their charge in semiconductors. The basic idea is to combine the characteristics of existing magnetic devices with semiconductor devices in order to realize a new generation of devices that are much smaller, more energy efficient, non-volatile, and much faster than presently available. The key requirement in the development of such devices is an efficient injection, transfer and detection of spin-polarized current from a ferromagnetic material into a semiconductor. Due to the well known problem of a resistance mismatch at metal/semiconductor interfaces, hindering an effective spin injection, much interest is concentrated on the development of room-temperature ferromagnetic semiconductors. The aim of this book is to shed some light on the origin of room temperature ferromagnetism in oxide-based DMS materials whether it originates from clusters or from uniformly distributed magnetic atoms.

Available in PDF, EPUB and Kindle. Book excerpt: Nanomagnetism and spintronics are two close subfields of nanoscience, explaining the effect of substantial magnetic properties of matter when the materials fabrication is realized at a comparable length size. Nanomagnetism deals with the magnetic phenomena specific to the structures having dimensions in the submicron range. The fact that the electronic transport properties of materials are dependent on the magnetic properties' artificial nanostructures, i.e., giant magnetoresistance (GMR) or tunneling magnetoresistance (TMR), has revolutionized spintronics science and technology. This book explains the concepts of nanomagnetism and spintronics by viewing the most recent research works from internationally distinguished research groups. Placing special emphasis on crucial fundamental and technical aspects of nanomagnetism and spintronics, it serves as a one-stop reference for universities offering postgraduate programs in nanotechnology or related disciplines. This unique book deals with all three stages required for conducting research in nanomagnetism and spintronics including fabrication, characterization and applications of nanomagnetic and spintronics materials, providing general concepts and an insightful overview of this subject for research students and scientists from different backgrounds investigating the multidisciplinary area of nanotechnology.

The following five chapters discuss the electrical properties observed in metal oxide-based semiconductors and the status quo of device-level developments in a variety of applications such as sensors, transistors, dilute magnetic semiconductors, and dielectric materials. The basic science and mechanism behind the optoelectronic phenomena are explained in detail, to aid readers interested in the structure–property symbiosis in semiconducting nanomaterials. In short, the book offers a valuable reference guide for researchers and academics in the areas of material science and semiconductor technology, especially nanophotonics and electronics.
