Dynamics of an Interacting Particle System: Evidence of Critical Slowing Down
Open accessAbstract
The dynamics of a magnetic particle system consisting of ultrafine Fe-C particles of monodisperse nature has been investigated in a large time window, ${10}^{\ensuremath{-}9}--{10}^{4}\mathrm{s}$, using M\"ossbauer spectroscopy, ac susceptibility, and zero field cooled magnetic relaxation measurements. By studying two samples from the same dilution series, with concentrations of 5 and $6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}\mathrm{vol}%$, respectively, it has been found that dipole-dipole interaction increases the characteristic relaxation time of the particle system at all temperatures investigated. The results for the most concentrated particle assembly are indicative of collective magnetic dynamics and critical slowing down at a finite temperature, ${T}_{g}\ensuremath{\approx}40\mathrm{K}$. Close to and below the transition temperature, an aging phenomenon is observed, another manifestation of collective magnetic dynamics.

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.
