Figure 1
Neutron diffraction patterns of Er3Cu4Sn4, collected on an E9 high-resolution diffractometer with λ = 2.815 Å, at (a) 7.9 K (the paramagnetic state), together with the difference patterns showing pure magnetic contributions, (b) 3.7–7.9 K and (c) 1.4–7.9 K. The open circles represent the experimental points. The solid lines indicate the calculated profiles and the difference between the obtained and calculated intensity (at the bottom of each diagram). The vertical bars indicate the positions of Bragg reflections (a) of nuclear origin corresponding to the main Er3Cu4Sn4 phase (first row) and to the impurity phases Er2O3 (second row) and Cu (third row), and those of magnetic origin corresponding to (b) the ordering of the Er magnetic moments occupying the 2c site and (c) the ordering of the Er magnetic moments occupying the 2c (first row) and 4i (second row) sites and the antiferromagnetic order in Er2O3 (third row). |
