Abstract
The infinite-range magnetization equation is solved for a three-component spin system involving cubic anisotropy of fourth, sixth, eighth and tenth degree. The longest possible non-reentrant sequences of second order transitions are I → (X) → (XY) → (X = Y) → (X = Y, Z) → (X = Y = Z) and I → (X) → (XY) → (XYZ) → (X = Y = Z), where the symbols denote non-vanishing magnetization components, for the eighth and tenth order Hamiltonians, respectively.
