Spin-glass-like ordering of the magnetic moments of interacting nanosized maghemite particles
Open accessAbstract
Samples of interacting nanosized maghemite particles have been studied by M\"ossbauer spectroscopy and magnetization measurements. The apparent blocking temperatures obtained from M\"ossbauer spectroscopy and zero-field-cooled magnetization curves are nearly identical, but the values obtained from measurements of the decay of remanence are much lower. These results are not in accordance with the N\'eel model for superparamagnetic relaxation, but can be explained by the formation of an ordered spin-glass-like state at low temperatures. At a critical temperature a transition to a superparamagnetic state takes place. By varying the average interparticle distance it is possible to change the ordering temperature.

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.
