Abstract
The intense small‐angle scattering of low‐energy neutrons by magnetic materials near the Curie temperature has been shown by Van Hove to be directly related to the appearance of large scale fluctuations in the spin density. We have measured the angular and energy distributions of 4.27‐Å neutrons scattered at small angles in iron and determined the spin correlation range 1∕κ1 and a parameter Λ associated with the lifetime of the fluctuations.
Our results confirm the recent observation of Jacrot, Konstantinovic, Parette, and Cribier that the scattering is not elastic even at the Curie temperature. We have found that κ12 varies as (T−Tcmath for 0°
