Critical scattering of neutrons from CoO

Abstract
The angular distribution of neutrons scattered from CoO just above the Néel temperature is observed and analyzed in the elastic approximation. It gives the correlation function for the direction of spins within each magnetic sublattice. The peaks observed are compared with those calculated from molecular field theory.
Résumé
La distribution angulaire des neutrons diffusés par CoO immédiatement au-dessus de la température de Néel est observée et analysée dans l'approximation élastique, donnant la fonction de corrélation pour la direction des spins dans chaque sous-réseau. Les raies observées sont comparées avec celles calculées dans l'approximation du champ moléculaire.
