Ising Model,lity, the entropy and the specific heat will be derived and discussed..In contrast to the one-dimnsional case, the two-dimensional model displays a phase transition between the paramagnetic and ferromagnetic spin ordering at a finite temperature ... First the existence of spontaneous magnetization w

Heisenberg Model,odel Hamiltonian..With the help of the simple molecular field approximation, we handle approximately the ferromagnet, antiferromagnet and ferrimagnet, without imposing any restrictions on the external parameters such as the temperature . and field ... As results, we obtain quantities such as magneti

Textbook 2009rdering for finite temperatures is investigated within a series of theoretical models, each of them considered for a very special class of magnetic materials. The book is written in a tutorial style appropriate for those who want to learn magnetism and eventually to do research work in this field. N

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
