- | The Ising model was originally devised as a simplified model of a ferromagnet, but is applicable also in a much broader sense. There is no need to refer to any ferromagnetic setup, but instead the Ising model can be defined completely general. | + | The Ising model was originally devised as a simplified model of a ferromagnet, but is applicable also in a much broader sense.
