Orientation superstructures are examined using the magnetic diffusion after‐effect, the squareness ratio R , and the induced anisotropy K u , in the ferrites: Mn 0.2 Fe 2.8 O 4.014 , Cu x Mg 1−x Fe 2 O 4 (0.09 ≦ x ≦ 0.69), Mn 1+ x O 4 (0.1 ≦ x ≦ 0.8) and Fe 1.95 Ni 0.95 Co x × × Zn 0.1−x O 4 (0.02 ≦ x ≦ 0.1). In the temperature zones where disaccommodation occurs (due to the ionic or electronic diffusion), a uniaxial anisotropy can be formed with a corresponding increase of R . It is shown that a new type of electron transfer: Cu + ↔ Cu 2+ is responsible for the magnetic after‐effect in Mg‐Cu ferrites.
