Direct Observation of Magnetic Relaxation in a Small Permalloy Disk by Time-Resolved Scanning Kerr Microscopy
Abstract
Magnetic oscillations were studied in a single, lithographically patterned disk ( $8\ensuremath{\mu}\mathrm{m}\mathrm{diam}\ifmmode\times\else\texttimes\fi{}0.1\ensuremath{\mu}\mathrm{m}\mathrm{thick}$) of permalloy placed in an in-plane biasing magnetic field, excited by subnanosecond pulses of perpendicular field. Local changes of the perpendicular magnetization component were detected by time-resolved scanning magneto-optical Kerr microscopy, allowing direct observation of the nonuniform spatial evolution of the magnetization. It was found that the modal frequency of the oscillations is very close to the ferromagnetic resonance frequency. The Landau-Lifshitz-Gilbert equation with damping constant equal to 0.008 describes broad features of the data, although departures due to the nonuniform response are also evident.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
