ResumoA quantitative discussion is given of recent paramagnetic diffuse neutron scattering data on bcc Fe above Tc. It is found that although the spatial spin correlation function has a weak tail of fairly long range the correlation between nearest neighbour spin directions is very small at 1.24Tc. It is concluded that the data are inconsistent with the giant short-range order hypothesis of Prange and Korenman, Capellmann and Sokoloff and another interpretation is given.
