摘要：

Using the property of rotational invariance of the free energy, F can be expanded as the sum of F//a the magnetocrystalline energy, F//m//e its derivative with respect to the symmetrical strains and F//r its derivative with respect to the rotations. This latter term, always ignored, provides a simple analytical expression of the magnetic torque for any given direction of the magnetization.
