Magnetic Materials

Magnetism is a quantum-mechanical phenomenon that shows up at every length scale, from atomic spins to hard drives and MRI machines, and this course tries to give you a coherent way to think across all of them rather than treating each application as a separate trick. You'll build up the theory starting from atomic origins and exchange interactions, then work through domains, anisotropy, and resonance techniques, with homework sets, a midterm, and a project plus final paper where you dig into a specific material or device. It's a graduate-level synthesis course that assumes you already know solid-state and quantum basics, and it's the natural entry point if you want to do research in spintronics, magnetic recording, or biomedical magnetic materials.
