A method to analyze the anisotropy constants of a two sublattice system with uniaxial anisotropy has been investigated by extending the Sucksmith and Thompson's method to higher order anisotropy terms. Using graphical analysis together with numerical calculation, the sublattice anisotropy constants of a two sublattice system are calculated. Using the method, a set of anisotropy constants for Pr-sublattice of Pr₂Fe₁₄B at 4.2 K has been obtained as K_(1Pr)=5210 J/㎏, K_(2Pr)=-7200 J/㎏, K_(3Pr)=-770 J/㎏, K_(4Pr)=4940 J/㎏ and K_(5Pr)=700 J/㎏ for N_(PrFe)=2.2 T/Am²㎏-¹. The magnetization calculated by an energy minimum method by using the sublattice anisotropy constants well reproduced the experimental results and satisfied the simulation assumptions.
