Magnetic neutron scattering in dilute AlMn alloy

Abstract

Neutron scattering studies were performed on an Al-0.5-at.%-Mn dilute alloy at $T=80\mathrm{}$ °K and $T=300\mathrm{}$ °K sample temperatures. The incoherent magnetic scattering cross section was measured using the Dubna pulsed reactor as a function of in-going neutron energy, at four scattering angles. The results show a nonzero magnetic moment on the Mn sites and a $\xi \sim 6$ Å radius oppositely polarized electron cloud around these atoms.
