Magnetic Materials & Devices – EE 396V
Magnetic materials play a key role in both present and future computing for storage and logic. This graduate-level course provides a foundation for understanding the materials, physics, and engineering behind magnetic devices. It starts with the fundamentals of magnetic materials, including both classical and quantum descriptions of the origin of magnetism in oxides and metals. We discuss the different energies at play in magnetic materials such as demagnetization energy, magnetocrystalline anisotropy, exchange energy, and dipolar coupling. We describe magnetic switching mechanisms and how spin structures arise, such as domain walls and topologically-protected skrymions. By the end of the course, we are able to understand existing breakthrough magnetic devices, as well as emerging phenomena that could be applied to future memory and logic devices.
- Review of Maxwell’s equations and of classical and quantum origins of magnetism
