(a) Temperature dependence of the magnetization of the Gd1−xAl2 compounds measured under an applied magnetic field H = 0.1 T: R′ = Er (blue, filled down triangles), Ho (green, filled circles) and Dy (red, filled triangles); and x = 0.25 (solid symbols); x = 0.5 (open symbols). (b) Comparison of the magnetization versus applied magnetic field curves of the pure RAl2 (solid symbols) and Gd0.5Al2 (open symbols) compounds for R′ = Er (blue, open down triangles), Ho (green, open circles) and Dy (red, open triangles). This figure is in colour in the electronic version of this paper. |
