Taking into account the anisotropy constants up to the sixth order the critical fields for the demagnetization mode of uniform rotation in uniaxial materials are derived. The boundary curves separating regions of material parameters with distinct critical behaviour are determined. The relation between uniform rotation and FOMP is discussed in the context of elementary catastrophe theory.
