    • While other sources of voltage have been proposed [see L. Berger, Phys. Rev. B 54, 9353 (1996)], previous work using GMR to sense time-varying magnetization motion indicates that GMR is the dominant source of ac or dc impedance change in spin-valve devices. For example, see Refs. 1 and 3. The measurement geometry makes inductive coupling between the device and waveguide negligible.

    • Knowing ΔR, and also which is the more likely of the two states, one can invert these spectra to determine the respective dwell times. However, because ΔR is a function of both current and field, this is not possible for switching rates faster than 1.5 GHz (our oscilloscope bandwidth).

    • This assumes that the damping and the out-of-plane component of M remain small. Simulations suggest that the second assumption is questionable for SMT-induced precessional modes.
