(a) Temperature dependence of the magnetization of the RAl2 compounds measured under an applied magnetic field H = 0.1 T. (b) Magnetization versus applied magnetic field curves of the RAl2 compounds recorded at T = 4.2 K. (c) Comparison of the magnetization of the RAl2 at T = 4.2 K and H = 5 T (black, filled circles) and the free-ion μ4f magnetic moments (red, open circles). (d) Comparison of the Curie temperatures of the RAl2 compounds (red, open circles) and the J(J + 1)(g − 1)2 dependence (black, filled circles) through the series.
