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.

Reviews the magnetic, electrical, dielectric and optical properties of oxide semiconductors with defect-induced magnetism Discusses growth and post-deposition strategies to grow oxide nanostructured materials such as oxide thin films with defect-induced magnetism Provides examples of materials with defect-induced magnetism such as zinc oxide, cerium dioxide, hafnium dioxide, and more

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.

The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) was enacted in India with the multiple objectives of providing employment in a rights-based framework, addressing rural poverty, checking migration, and building rural infrastructure. As such, every year around 15–20 per cent of households in India overall and 30 per cent in rural India receive some form of employment share under the MGNREGA programme. This volume looks at various aspect of the scheme, its linkage with employment, agricultural wages, livelihood and food security, gender issues, and migration in rural India. It also discusses challenges in implementation, hurdles and the relative successes of the scheme. Based on primary survey data from 16 major states in the country, the findings of the study provide key insights into MGNREGA and assess the implications for other welfare-oriented programmes. Rich in empirical data, this volume will be useful to scholars and researchers of political economy, economics, agriculture, rural development and sociology, as well as policymakers and nongovernmental organisations.

This volume examines the transitions in Indian agriculture since the 1980s, and emphasizes upon the role of neoliberal policies and their impact. The essays presented here deal with a range of pertinent and contemporary issues, including global food security, livelihoods of agricultural labourers, and public and private investment. These weave together glimpses of the impasse faced by petty commodity producers (marginal and small farmers) and their subsequent economic distress and social exclusion. Comprehensive in analysis, this book will be useful to scholars and researchers of agricultural economics, political economy, political science and public policy.

This book provides an overview of the applications of ion beam techniques in oxide materials. Defects in these oxide materials also lead to magnetism in non-magnetic materials or to a change of magnetic ordering in magnetic materials.
