Résumé

We have performed a differential polarisation analysis neutron scattering experiment of β oxygen to measure the magnetic part of the scattering and determine its magnetic structure. We have checked all the models proposed for β oxygen and all those compatible with crystal symmetry. The model which fits the experimental neutron profile best is a two dimensional short range order, a helix propagating perpendicularly to the three fold axis with an angle close to 140 ° between neighbouring molecules and with a correlation length of 5 Å.
