The Ising model, developed by Dr. Ernst Ising is used for
modelling ferromagnetic and anti-ferromagnetic materials
I The model represents a lattice occupied by atoms which can
each have dipole moments or spins
I The model predicts a second order phase transition occuring
at the Curie temperature for dimensions higher than 1
I Phase transition is identified from ensemble properties and
compared with the theoretical model which has been solved
exactly for zero external field
