A model of two-valued local spins with specified lattice couplings and external field. It captures symmetry breaking and criticality in its universality classes but is not a literal microscopic description of every magnet.

This is an authored directed relation from the source endpoint to the target endpoint.
The Ising model idealizes uniaxial magnetic degrees of freedom as two-valued lattice variables and captures ferromagnetic symmetry breaking and criticality in applicable universality classes.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.
