Book excerpt: This dissertation presents a Monte Carlo simulation study of fluctuations and magnetization reversal in thin (5, 10 and 20 nanometers thin), permalloy (Ni 81 Fe 19 films. The study shows how the presence of vertical end pinned domains (VEPDs) in these films leads to nucleation of vortices and anti-vortices. We also show how the vertical edge pinned domains (VEPDs) lead to the formation of horizontal edge pinned domains (HEPDs) in the course of a films magnetization reversal. A mechanism for HEPD-reversal is discovered, involving the creation and motion of a head-to-head domain wall. When vortices nucleate to initiate a films magnetization reversal the switching field varies linearly with temperature, and for reversal that starts with growth of VEPDs switching field has a T 2 dependence. Novel images of spin configuration are used to show fluctuations and magnetization reversal. Our thin film's easy-axis is parallel to the length of the film. For a 5 nm thin film, the author shows that roughness in the edges parallel-to-the-easy-axis increases the switching field of the film in comparison to the switching field of a control film--a similar film with straight edges--by 3.9% in an aspect ratio 5 film and by 6.7% in an aspect ratio 1.5 film. When roughness, or etching, is in the edges perpendicular-to-the-easy-axis the switching field of such films is less than that of the control film by 2.8% and by 4.2% in the respective cases. The mechanisms described in this work are of importance in computer memory and data-storage industry, as well for sensor and circuit isolator applications.

Book excerpt: Metallic films play an important role in modern technologies such as integrated circuits, information storage, displays, sensors, and coatings. Metallic Films for Electronic, Optical and Magnetic Applications reviews the structure, processing and properties of metallic films. Part one explores the structure of metallic films using characterization methods such as x-ray diffraction and transmission electron microscopy. This part also encompasses the processing of metallic films, including structure formation during deposition and post-deposition reactions and phase transformations. Chapters in part two focus on the properties of metallic films, including mechanical, electrical, magnetic, optical, and thermal properties. Metallic Films for Electronic, Optical and Magnetic Applications is a technical resource for electronics components manufacturers, scientists, and engineers working in the semiconductor industry, product developers of sensors, displays, and other optoelectronic devices, and academics working in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Materials development has reached a point where it is difficult for a single material to satisfy the needs of sophisticated applications in the modern world. Nanocomposite films and coatings achieve much more than the simple addition of the constitutents OCo the law of summation fails to work in the nano-world. This book encompasses three major parts of the development of nanocomposite films and coatings: the first focuses on processing and properties, the second concentrates on mechanical performance, and the third deals with functional performance, including wide application areas ranging from mechanical cutting to solar energy and from electronics to medicine.

Book excerpt: The main theme of this book is micromagnetism and microstructure as well as the analysis of the relations between characteristic properties of the hysteresis loop and microstructure. Also presented is an analysis of the role of microstructure in the fundamental magnetic properties (for example, magnetorestriction or critical behaviour) of crystalline and amorphous alloys. The authors apply the theory of micromagnetism to all aspects of advanced magnetic materials including domain patterns and magnetization processes under the influence of defect structures. Coverage includes modern developments in computational micromagnetism and its application to spin structures of small particles and platelets. It will be of interest to researchers and graduate students in condensed matter, physics, electrical engineering and materials science, as well as to industrial researchers working in the electrotechnical and recording industry.
