Teaching
27-545 / 27-745 · Magnetism in Materials
The course runs in two halves. The first builds the fundamentals: magnetostatics, how a magnetic moment is actually measured, the atomic origins of magnetism, diamagnetism and paramagnetism, magnetic ordering and exchange, domains, anisotropy, and magnetotransport. The second turns to materials and what they are good for: nanoparticles and thin films, data storage, magneto-optics, magnetocalorics, superconductors, magnetic semiconductors and insulators, multiferroics, frustrated and exotic magnetism, and the neutron and muon probes used to study all of it.
27-432 · Electronic Properties of Materials
The physical principles behind the electronic and thermal behavior of solids, with the emphasis on metals and semiconductors. Quantum and statistical mechanics applied to solids, chemical bonding and the origin of energy bands, electrons and phonons carrying charge and heat, carrier generation, drift and diffusion, and what junctions and interfaces do to all of it. Devices appear to illustrate the principles rather than as the subject. The course assumes no prior chemistry coursework and introduces the chemical ideas it needs as it goes.
27-445 · Structure, Properties, and Performance Relationships in Magnetic Materials
Magnetism in materials, with the emphasis on the properties and phenomena that get used. The first half covers magnetostatics, the atomic origins of magnetism, ferromagnetic, ferrimagnetic and antiferromagnetic ordering, exchange, anisotropy, and magnetotransport. The second half covers applications and the materials classes behind them: data storage, magneto-optics, magnetocalorics, multiferroics, ferrites, superconductors, magnetic semiconductors and insulators, and the scattering methods used to see magnetic structure. Now superseded by 27-545 / 27-745.
