We investigate an effect of configurational anisotropy in highly symmetric soft ferromagnetic nanoparticles. Using the micromagnetic variational principle and methods of Γ-convergence, we show that in ferromagnetic generalized right prisms with symmetry,1 there is a finite number of preferred magnetization directions and that these directions are independent of the shape of the magnet. This result provides a rigorous justification of work by Cowburn and Welland.
