(a) Comparison of the temperature dependence of the magnetization measured at 5 T by using a standard SQUID magnetometer (dotted lines) and that derived by combining both the rare-earth L2-edge and the transition-metal K-edge XMCD spectra (open symbols) in the case of ErFe2 (black, squares), Er(Fe0.75Al0.25)2 (red, circles), Er(Fe0.5Al0.5)2 (green, triangles), ErCo2 (blue, inverted triangles) and HoCo2 (purple, diamonds). (b) Temperature dependence of the magnetization of the rare-earth (solid symbols) and transition-metal (open symbols) sublattices, MR and MT, determined from XMCD spectra: ErFe2 (black, squares), Er(Fe0.75Al0.25)2 (red, circles), Er(Fe0.5Al0.5)2 (green, triangles), ErCo2 (blue, inverted triangles) and HoCo2 (purple, diamonds). The dotted lines are a guide for the eye. |
