Figure 4
(a) Thermal evolution of the Er3Cu4Sn4 neutron diffraction pattern, based on the data collected between 1.75 and 7.86 K. The 2θ range from 5 to 25° is shown (E6 diffractometer, λ = 2.432 Å). (b) Temperature dependence of the Er magnetic moments located in the 2c (k1 = [0, 0, ]) and 4i (k2 = [1, 0.4667 (1), ]) sites. In the latter case, the amplitude of modulation is presented as the magnetic structure is incommensurate. |
