The switching process of magnetic recording NiFe thin films is
considered. First, it is illustrated through numerical
micromagnetic simulations that precessional switching process
can be reasonably considered a quasiuniform process, while in
conventional switching process, domain nucleation and wall
motion are involved in the magnetization reversal dynamics.
Second, we used analytical uniform mode theory of precessional
switching to predict the duration of the applied field pulse.
We verified that the uniform mode theory provides reasonably
good indications on the quasiuniform precessional switching
