Abstract

This chapter initially reviews key formulas and concepts in magnetization dynamics, primarily in ferromagnets. This is followed by a discussion of the kinds of initial measurements that one might use to characterize an unknown magnetic sample. Then, ferromagnetic resonance is developed in more detail, introducing magnetic damping and discussing both field-swept and frequency-swept measurements. A second common technique for measuring magnetization dynamics, Brillouin light scattering, is then presented along with recent examples. The emphasis throughout the chapter is on thin films and nanostructures.
