We study the magnetic short range order (MSRO) in ${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Cr}}_{x}\phantom{\rule{4pt}{0ex}}(0\ensuremath{\le}x\ensuremath{\le}0.15)$ where an inversion of atomic short range order (ASRO) occurs at ${x}_{C}=0.11(1)$.

In this paper a neutron scattering study of local order and magnetic properties of the Fe 1− x CO x amorphous system is presented. A wide momentum transfer range has been used for studying local order. The better resolution associated with higher n

We have performed different neutron diffuse scattering measurements in ${\text{Fe}}_{1\ensuremath{-}x}{\text{Cr}}_{x}$ solid solutions, in a concentration range $0lxl0.15$, where the atomic distribution shows an inversion of the short range order. By

The positional short-range order, SRO ⊥ , perpendicular to the nematic director n has been studied in the fibre-type nematics, n BABAs, by neutron diffraction. SRO ⊥ is found to be dependent on other types of nematic short-range order but not on

The authors present the results of Rietveld refinements of neutron investigation on the magnetic structure of Bi2CuO4. On each copper site they measured a magnetic moment of m=0.45+or-0.02 mu B at T=19 K, incompatible with the determination of m=0.93

Neutron measurements on FeMn and FeTi alloys with impurity concentration lower than 3 at. % were done at liquid‐nitrogen temperature by using polycrystalline samples quenched from the melt. The most concentrated FeMn alloy exhibited an atomic short

Recently, considerable theoretical effort has been directed toward a general understanding of the thermally induced concentration and magnetic moment fluctuations in alloys and the relationship of these fluctuations to alloy phase stability. The atom

Results of elastic diffuse scattering of polarized neutrons with 4.25-\AA{} wavelength on Ni-Ti with 3.87 and 7.72 at.% of Ti and Fe-Ti with 0.84, 1.33, and 1.73 at.% of Ti are reported. The data indicate quite different behavior of the impurity in t
