Exchange Interaction,spontaneous collective ordering of the permanent magnetic moments, that exist in ferro-, ferri- and antiferromagnetic materials. For this, we discuss first two phenomenological theories, namely, the concept of the exchange field and the Weiss’ theory of ferromagnets. For collective magnetism, the so
