The magnetization processes of the rare‐earth and Fe sublattices in R 2 Fe 14 B compounds (R = Tb, Dy, Ho, Er, and Tm) along the principal crystal axes at 0 K in fields up to 200 kOe are analysed. The analysis based on the classical three‐sublattice model reproduces fairly well the magnetization processes which are predicted by the analysis based on the crystalline electric field model. The noncollinearity between the magnetic moments of the rare‐earth and Fe sublattices is striking during the magnetization processes, and the Sucksmith‐Thompson method widely used for the evaluation of the magnetocrystalline anisotropy constants cannot be used for the R 2 Fe 14 B compound system.
