We have used neutron powder diffraction to demonstrate the existence of long-range antiferromagnetic order of Ising-like Dy moments in the DyCd6 quasicrystal approximant phase. This cubic compound undergoes a slight distortion to a monoclinic cell at

Earlier Mössbauer investigations of rare earth chromates RCrO4 with R = Gd and Tm were interpreted in terms of a superposition of two sub-spectra (approx. 4:1 area ratio), despite there being only a single crystallographic R(4a) site. In addition, t

Previously, the bulk magnetisation of polycrystalline DyNiAl4 was found to reach barely half its expected saturation value with a 9 T applied field. New inelastic neutron scattering and 161Dy-Mössbauer spectroscopy results suggest that the crystal f
