Al-4(Cr, Fe): single crystal growth by the Czochralski method and structural investigation with neutrons at FRM II
Zeitschrift Fur Kristallographie 224(1-2): 109-111
A single crystal of Al-4(Cr,Fe) with composition Al78Cr19Fe3 grown by the Czochralski method was studied by neutron diffraction for the first time. As a preliminary result the neutron diffraction experiment suggests a body-centered orthorhombic space group Immm with a = 1.24985(3) nm, b = 1.25500(3) nm and c = 3.0512(2) nm as found by Deng et al. (Pearson symbol: oI366-59.56)  using single crystal X-ray diffraction. Additionally, more or less diffuse maxima at positions with k = n/2 (n = odd) are clearly observable.
