Available in PDF, EPUB and Kindle. Book excerpt: Bit patterned media (BPM) have received increased attention in recent years as the primary candidate for 1 Terabit/in2 or higher recording density. A patterned media consists of an array of well-defined magnetic nanostructures, each of which can store one bit of data. In the simplest scheme, the structures could be magnetic pillars and dots with a single easy axis of magnetization. The direction of magnetization is interpreted as a binary 1 or 0. Some of the main technical issues in the BPM include the difficulty in fabricating small nano-island arrays in a periodic fashion over large areas, reliability/reproducibility of magnetic bit characteristics, wear and head flyability issue which is associated with the media surface roughness, and processing cost. This thesis deals with investigation of various fabrication approaches, nanostructural features, and magnetic properties for the bit patterned media. In Chapter 1, the science and technology of patterned magnetic recording media are discussed. In Chapter 2, fabrication of an array of high-coercivity magnetic Co/Pd multilayered islands using pre-patterned Si nanopillars template is described. The Si nanopillars have been prepared by advanced electron beam lithography (EBL) and reactive ion etching (RIE). In Chapter 3, the flying instability of the read/write recording head-slider on the topographically rough surfaces of the nano-patterned media is discussed, and technical approaches to overcome such a problem is described, such as planarization of nanopatterned topography by refilling the trenches and flatten the surface of the BPM. I have investigated the head flyability on BPM by fabricating nano pillar geometry with different topography. For flyability testing that requires a relatively large area, I have also fabricated nano pillars on 2.5 inch glass disks with a distribution of pillar size and periodicity using the "silver ball-up process" and RIE. The process, structure and properties of planarized vs. non-planarized nano fabricated and imprinted BPM, are described in Chapter 4. A Si substrate was spin-coated with a thin PMMA layer, and a periodic island array was made by nano-imprinting lithography (NIL) with the patterned nanofeatures. The subsequent pattern transfer to the Si substrate was performed by using RIE process. A Co/Pd multilayer film was sputtered on the pre-patterned substrate. A HSQ layer was first spin coated on the patterned media to fill the trenches and subsequently re-etched by RIE to remove the overfilled regions on the substrate for planarization. In Chapter 5, the effect of magnetic island geometry on switching field distribution is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is a 'catch-all' description of activities at the level of atoms and molecules that have applications in the real world. A nanometre is a billionth of a metre, that is, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques. This book presents carefully selected abstracts of the last 5 years in this frontier field. Special access is provide by author, title and subject indexes.

Available in PDF, EPUB and Kindle. Book excerpt: In the past 30 years, magnetic research has been dominated by the question of how surfaces and interfaces influence the magnetic and transport properties of nanostructures, thin films and multilayers. The research has been particularly important in the magnetic recording industry where the giant magnetoresistance effect led to a new generation of storage devices including hand-held memories such as those found in the ipod. More recently, transfer of spin angular momentum across interfaces has opened a new field for high frequency applications.This book gives a comprehensive view of research at the forefront of these fields. The frontier is expanding through dynamic exchange between theory and experiment. Contributions have been chosen to reflect this, giving the reader a unified overview of the topic. - Addresses both theory and experiment that are vital for gaining an essential understanding of topics at the interface between magnetism and materials science - Chapters written by experts provide great insights into complex material - Discusses fundamental background material and state-of-the-art applications, serving as an indispensable guide for students and professionals at all levels of expertise - Stresses interdisciplinary aspects of the field, including physics, chemistry, nanocharacterization, and materials science - Combines basic materials with applications, thus widening the scope of the book and its readership

Book excerpt: This book is about thin films; what they are, how they are prepared, how they are characterized, and what they are used for. The contents of this book not only showcase the diversity of thin films, but also reveals the commonality among the work performed in a variety of areas. The chapters in this volume are based on invited papers presented by prominent researchers in the field at a Symposium on "Thin Films: Preparation, Characterization, Applications" at the 221st National Meeting of the American Chemical Society held in San Diego, California. The coverage of the symposium was extensive; topics ranged from highly-ordered metal adlayers on well-defined electrode surfaces to bio-organic films on non-metallic nanoparticles. An objective of this book is for the readers to be able to draw from the experience and results of others in order to improve and expand the understanding of the science and technology of their own thin films systems.

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.
