Query: The effect of confinement on thermally induced fluctuations in
  nanomagnets   We study the magnetization dynamics in nanomagnets excited by stochastic
magnetic fields to mimic temperature in a micromagnetic framework. The effect
of confinement arising from the finite size of the structures is investigated,
and we visualise the spatial extension of the internal magnon modes.
Furthermore, we determine the temperature dependence of the magnon modes, and
focus specifically on the low frequency edge modes, which are found to display
fluctuations associated with switching between C- and S-states, thus posing an
energy barrier. We classify this fluctuating behaviour in three different
regimes, and calculate the associated energy barriers using the Arrhenius law.
