To develop an in depth understanding of the physics, materials issues and technology of magnetism, spintronics and related applications. The course will cover fundamental concepts from classical and quantum theories of magnetism, to modern micromagnetics and spin-dependent transport. This will also discuss advanced magnetic storage, random access memory and various applications of magnetic sensors for field sensing.
The course will be self-contained, but prior exposure to the some or all of the following will be helpful. ENEE 380 or equivalent upper undergraduate electro-magnetostatics, ENEE690 or equivalent graduate level course in quantum mechanics is beneficial but not necessary.
Undergraduate electrostatics, magnetostatics, elementary quantum theory of atoms.
