"Diffuse neutron scattering study of disordered A72Co16Ni12 quasicrystals up to 1000 degrees C";
Applied Physics A: Materials Science & Processing, 74 (2002), S. 998 - 1000.

Disordered decagonal Al72Co16Ni12 quasicrystals
were investigated by recording diffuse neutron scattering at
instruments D10 and IN8/ILL up to 1000 ◦C. This neutron
work supplements X-ray-diffraction investigations, which do
not provide a scattering contrast of the transition metals.
Moreover, diffuse scattering of inelastic origin could be suppressed, within the resolution limits, by using an analyser.
The temperature dependence of the diffuse scattering in the
quasiperiodic plane indicates complex re-ordering processes.
A one-dimensional superorder along the unique axis, reflected by diffuse layers perpendicular to it, dissolves at
950 ◦C; short-range-order maxima remain visible at 980 ◦C.
