“…The intensities were divided by the squared magnetic scattering factor and normalized to Laue units. A magnetic moment of 4 B per manganese atom 24,25 and the magnetic form factor according to Shull et al 26 were used. At the 2k F positions, the recalculated intensity amounts to ϳ3.3 L.u.…”

Elastic diffuse neutron scattering from Cu-17 at.% Mn was measured within three planes of reciprocal space, at room temperature and at 11 K (far above and below the spin-glass temperature of 71 K) to determine the atomic and magnetic short-range order parameters. Using two samples with frozen-in states of thermal equilibrium of 483 and 553 K, respectively, the antiferromagnetic character of the spin glass was found to be robust against changes in the degree of atomic order while the ferromagnetic character is rapidly reduced with lower atomic order. This confirms conclusions of ab initio calculations by Ling et al.

“…Around the same time neutron scattering measurements by Meneghetti and Sidhu [2] showed that for compositions with 4 70 at% Mn the alloys exhibited anti-ferromagnetism, while for compositions with o70 at% Mn only a diffuse peak near (1 0 0) indicated lack of magnetic long-ranged ordering. A series of later neutron scattering experiments could not resolve the exact nature of the magnetic implications of this diffuse peak [3][4][5][6][7]. Some later work [8][9][10][11][12] indicated the existence of both short-ranged as well as long-ranged atomic and magnetic correlations.…”

“…These equations allowing for the multiple scattering experiments have proved useful in calibrating LONGPOL, and in calculating true NSF and SF cross sections from a number of weakly magnetic Mn alloys (e.g. Campbell, Hicks & Wells, 1983;Harders, Hicks & Smith, 1983).…”

Multiple scattering in neutron polarization analysis experiments

A simple analytic method to correct the experimentally observed spin-flip and non-spin-flip scattering cross sections in neutron polarization analysis experiments for the effects of multiple scattering is presented. From known parameters of the constituent elements of a specimen and from the measured experimental cross sections the single scattering cross sections can readily be determined. This is particularly useful in situations where the scattering is isotropic or exhibits only slight angular dependence.
