Magnetic materials have fascinated humankind for many years. The aim of this lecture is to describe how magnetic materials have helped to shape our world, in data-storage, magneto-optical devices, high-power electromotors, etc, and also in our understanding of many-body systems.
From descriptions by the ancient Greeks and the invention of the compass, probably in China, magnetism has become one of the corner stones of modern science and is central to many technologies. Recent advances, closely related to research at the University of Southampton, will be highlighted such as materials patterned on nanometer length scales: nano-magnets, superior magnetic (magnonic) metamaterials and spintronics – using the spin of conduction electrons to carry quantum or classical information. These developments promise a bright future for magnetism.
