Antiferromagnetic spin correlations in the Zn-Mg-Ho icosahedral quasicrystal
Abstract
Magnetic diffuse scattering in the Zn-Mg-Ho icosahedral quasicrystal has been studied by neutron scattering over a wide Q range using a single-quasicrystalline sample. It was found that the diffuse scattering obeys the icosahedral symmetry, and appears as satellite peaks of the intense nuclear Bragg reflections. The diffuse-scattering patterns were successfully accounted for by assuming short-range spin correlations in a six-dimensional hypercubic crystal with a magnetic modulation vector q=(34,0,0,12,34,12)a*. A possible origin for the six-dimensional spin correlations is discussed.
