| Learning objectives | Introduction to Magnetism and Magnetic Materials: In this lecture, we will embark on an exploration of the captivating world of magnetism, a phenomenon that has shaped both our understanding of physics and the development of numerous technologies. The topics to be covered include: 1. Introduction & History of Magnetism: We'll begin by tracing the origins and historical milestones of magnetism, understanding how this natural phenomenon has been observed and harnessed throughout human history. 2. Magnetostatics: The principles of static magnetic and magnetization fields will be covered, including the fundamental laws that govern them but also including forces on magnetic tips and particles which are of importance for magnetic force microscopy or biomedical applications. 3. Atomic Magnetism: An in-depth examination of how magnetism arises at the atomic level, focusing on the behavior of electrons and the nature of magnetic dipoles. 4. Magnetism of Interacting Atoms: We'll explore how magnetic interactions between atoms contribute to the overall magnetic properties of materials, including various types of magnetic ordering. 5. Magnetic Anisotropy: This chapter will focus on the directional dependence of magnetic properties, elucidating how materials or magnetic multilayers can preferentially magnetize along specific axes. 6. Magnetic Domains: Understanding the arrangement of magnetic moments within materials through the study of domains, key to the behavior of ferromagnetic substances. 7. Magnetization Processes: We'll delve into the processes by which materials become magnetized and demagnetized, and the accompanying phenomena such as hysteresis. 8. Imaging Methods: A look at various methods used to image magnetic structures, ranging from traditional techniques to state-of-the-art technologies. 9. Skyrmions: This section will introduce skyrmions, unique topological entities, and their significance in the field of magnetism. 10. Spintronics: We'll conclude with an exploration of spintronics, a cutting-edge field that exploits the intrinsic spin of the electron to develop novel electronic devices. Each chapter of this lecture will encompass specific applications, a review of relevant magnetic materials, and a detailed exploration of the experimental methods used to evaluate magnetic properties. This comprehensive approach ensures a holistic understanding of both the theoretical concepts and their real-world applications, fostering a connection between the abstract principles of magnetism and tangible technological innovations. Together, these chapters offer a comprehensive view of the field of magnetism, from its historical roots to the most modern advancements. Whether you're new to the subject or seeking to deepen your understanding, this lecture promises a fascinating journey through the magnetic world. |
