Résumé
La variation de l'aimantation alternée avec la température et le champ magnétique dans le système "spin-flop" CsMnBr3.2D2O a été étudiée par diffraction neutronique. Le diagramme de phase magnétique a été obtenu. Les valeurs des exposants critiques β ≥ et β ⊥ sont respectivement 0.321 (6) et 0.326(7).


Abstract
The dependence of the staggered magnetization on temperature and magnetic field in the spin-flop system CsMnBr3.2D2O was studied by means of neutron scattering. The magnetic phase diagram is reported. The critical exponents β ≥ and β ⊥ are found to be β ≥ = 0.321 (6) and β ⊥ = 0.326(7)
