Abstract

In a recent paper (Acremann et al 2000 Science 290 492) the precessional trajectory of the magnetization vector was imaged with spatial resolution as a function of the time elapsed after a magnetic field pulse was applied. The most surprising observations-the reversal of the magnetic excitation upon reflection from the boundary and the spatial non-uniformities of the precessional mode-have ...
