Studies of the ionic ferromagnet (LaPb)MnO3 III. Ferromagnetic resonance studies
Abstract
Ferromagnetic resonance has been observed in single crystals of the family La 1−x Pb x MnO 3 with 0.25 < x < 0.45 from 13 to 25 GHz and in the temperature range from 77 to 430 °K. The line width, ΔH, exhibits a sharp minimum accompanied by an isotropic shift in the resonance line at a critical temperature, T c. T c is dependent on the concentration of Mn 4+ and has been related to the Curie temperature. The shift in the peak of the resonance line at T c can be described by effects related to the formation of a spin-polarized conduction band. The line shape is asymmetric at high temperatures, ~T c, and at low temperatures, T ~ 77 °K. This asymmetric behavior of the line is probably due to transport properties of the conduction-band electrons.

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.
