AbstractMagnetic ordering of the orthorhombic Er3Cu4X4 (X = Si, Ge, Sn) system has been studied using both 119Sn and 166Er M�ssbauer spectroscopy, combined with neutron diffraction. We observe two distinct ordering events for the erbium moments on the 2d and 4e sites (TN (Er 2d)>TN (Er 4e)) and confirm that the Er 2d moments are larger than those on the Er 4e site. Comparison of neutron diffraction with 166Er M�ssbauer spectroscopy shows that the ordering of the Er 4e moments is far from complete, even at 0.7 TN, causing neutron diffraction analysis to severely underestimate the Er 4e moments in the Er3Cu4X4 system.
