The scaling equation of state for ferromagnets with interactions of cubic symmetry is derived to first order in ε=4-d, where d is the dimensionality of space. Finite susceptibilities are found at zero field below Tc. These diverge, however, as the number of spin components approaches nc (3.13 at ε=1) from above, where the cubic fixed point coincides with the usual Heisenberg fixed point.
