It is important, in considering certain physical properties, to allow for the existence of non‐linear anisotropy. Using magnetocrystalline anisotropy as an example, the role of symmetry is discussed in relation t o the description of non‐linear anisotropy and to the analysis of the corresponding experimental data (with particular reference to uniaxial and cubic symmetry). The advantages of using orthonormal functions, such as spherical harmonics, are demonstrated, both in general terms and also by specific application t o experimental data on magnetocrystalline anisotropy.
