(a) The field dependence of the magnetic distance distribution function Pmag(r) at 280 K. The Pmag(r) values were computed numerically via an indirect Fourier transform (IFT) of the experimental dΣmag/dΩ data shown in Fig. 4(b). Note that for comparison with the results obtained at lower temperatures, as summarized in Appendix C, the Pmag at each field has been normalized by the maximum peak intensity value obtained at remanence. (Inset) A comparison between the experimental dΣmag/dΩ plotted in Fig. 4(b) (coloured open circles) and the reconstructed dΣmag/dΩ based on the IFT of the numerically computed Pmag shown in Fig. 5(a) (coloured solid lines). (b) The corresponding magnetic correlation function Cmag(r) = Pmag(r)/r2 (semi-logarithmic sale). |
