    • note
    • It has quite recently been shown [65,66], experimentally and theoretically, that efficient magnetization switching can be triggered by transverse field pulses of a duration that is half the precession period.

    • note
    • Rigorously, the switching of magnetization through a change of its magnitude cannot, however, be explained within the single-spin approximation (see Section 4).

    • A spontaneous breaking of a continuous symmetry entails the existence of a massless mode, that is a zero-energy fluctuation, called the Goldstone mode: This is known as the Goldstone theorem.

    • Similarly, it was found in Ref. [50] that the reversal of the two dipoles considered is a two-stage process with an intermediary metastable antiparallel state.
