The magnetization order parameter in magnetic nanostructures can be excited by torques from internal and external magnetic fields as well as electrically induced spin currents. Conversely, a time-varying magnetization emits spin currents that couple spatially separated magnetic elements in circuits and devices. Here we review the principles of time-dependent magnetoelectronic circuit theory, a simple yet effective theoretical framework that captures the essential physics and in favourable limits allows quantitative description of phenomena such as Gilbert damping enhancement, coupled magnetization dynamics, and the spin battery effect.
