Chapter 1: Quantized Spin-Wave Modes Due to Lateral Confinement (4,428k)

This book presents recent scientific achievements in the investigation of magnetization dynamics in confined magnetic systems. Introduced by Bloch as plane waves of magnetization in unconfined ferromagnets, spin waves currently play an important role for description of very small magnetic systems ranging from microelements, building the basis for magnetic sensors, down to magnetic nano-contacts.

Spin wave confinement effect was experimentally discovered in the 1990s in permalloy microstripes. The diversity of systems where this effect is observed has been steadily growing since then, most of which will be addressed in this book.

The book includes six chapters which originate from different groups of experimentalists and theoreticians dominating the field since the discovery of the effect. Different chapters of the book reflect different facets of spin wave confinement, providing a comprehensive description of the effect and its place in modern magnetism. It will be of value for scientists and engineers working on magnetic storage elements and magnetic logic, and is also suitable as an advanced textbook for graduate students.

Contents:

• Quantized Spin-Wave Models Due to Lateral Confinement (S O Demokritov & V E Demidov)
• Brillouin Light Scattering Study of Spin Dynamics in Patterned Nano-Elements: From Single-Layer to Multilayered Structures (G Gubbiotti et al.)
• Non-Uniform Magnetization Dynamics in Ultra-Small Ferromagnetic Planar Elements (V V Kruglyak et al.)
• Mode Structure of Ferromagnetic Squares (M Bailleul & C Back)
• Spin Waves in the Inhomogeneous Internal Field of Nanostructured Rings (D Grundler et al.)
• Localized Spin Wave Modes Excited by Spin-Polarized Current (A N Slavin & V S Tiberkevich)

Readership: Graduate and post-graduate students in physics, engineers working in the field of magnetic sensors, and non-experts who are interested in magnetic dynamics.

"I greatly enjoyed reading this book, which covers a new, vigorously developing part of magnetism. Demokritov has managed to encourage the leading players in the field to give their views of the current status quo and to share with us their visions of the future development of the spin-wave studies in nanostructures. The book not only explains the physics of spin waves to the young students, but it also brings a lot of valuable facts and ideas to the experts in magnetic dynamics."

Key Features:

• Offers a complete overview of spin waves that plays a crucial role in developing the fundamentals ranging from magnetic sensors, hard disks to magnetic nano-contacts
• Presents extensive contributions by world-class authors and chapters are written in a high pedagogical value that could be used as an advanced graduate textbook
• Prof. Sergej Demokritov was listed in the Scientific American 50 award for outstanding research, business and technological leadership
