Defect-Induced Magnetism in Oxide Semiconductors provides an overview of the latest advances in defect engineering to create new magnetic materials and enable new technological applications. First, the book introduces the mechanisms, behavior, and theory of magnetism in oxide semiconductors and reviews the methods of inducing magnetism in these materials. Then, strategies such as pulsed laser deposition and RF sputtering to grow oxide nanostructured materials with induced magnetism are discussed. This is followed by a review of the most relevant postdeposition methods to induce magnetism in oxide semiconductors including annealing, ion irradiation, and ion implantation. Examples of defect-induced magnetism in oxide semiconductors are provided along with selected applications.

This book is a suitable reference for academic researchers and practitioners and for people engaged in research and development in the disciplines of materials science and engineering.

Coffee is a major commodity of export in developing countries. In India, it generates significant revenues besides providing employment to many. This book critically looks into various aspects of the coffee production and marketing industry and its potential for promoting sustainable development, poverty alleviation and providing decent work.

The small-holder dominated coffee sector is under unprecedented crisis attributed to a host of factors like declining productivity, incidences of new pests and diseases, adverse price trends and issues related to global warming induced climate change. Supported with primary survey and secondary data, this book explores challenges related to coffee production and its economic importance in India. It analyses factors affecting productivity of Robusta and Arabica varieties of coffee— and offers important inferences about the relationship between age and productivity of the plants and factors that guarantee high productivity. The book also sheds light on institutional interventions and the use of IT applications, along with online trading, in the coffee sector.

Comprehensive and insightful, the book will be of interest to students and researchers of agriculture studies, agricultural economics, horticulture with a special focus on spices and plantation, sustainability studies, development studies and crop science. It will also be useful to stakeholders of plantation crops, such as, growers, as well as policy makers, processors, traders and exporters at different levels.

This book provides an overview of the applications of ion beam techniques in oxide materials. Oxide materials exhibit defect-induced physical properties relevant to applications in sensing, optoelectronics and spintronics. Defects in these oxide materials also lead to magnetism in non-magnetic materials or to a change of magnetic ordering in magnetic materials. Thus, an understanding of defects is of immense importance. To date, ion beam tools are considered the most effective techniques for producing controlled defects in these oxides. This book will detail the ion beam tools utilized for creating defects in oxides.
