%X Evidence is summarized attesting that the standard exchange field theory of ferromagnetism by Heisenberg has not been successful. It is replaced by the crystal field and a natural assumption that spin orientation is inexorably associated with the orientation of its carrier. It follows at once that ferromagnetic state is a property of the crystal structure and that both ferromagnetic phase transitions and magnetization must involve a structural rearrangement. The mechanism of structural rearrangements in solids is nucleation and interface propagation. The new approach accounts consistently for ferromagnetic state and its manifestations.
