Abstract
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

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.
