Magnetic models
A magnetic model system is one with a simple lattice structure, populated by spins with one, two or three components, which is susceptible to precise theoretical analysis. Although every real sample has a finite, defective, threedimensional lattice, populated by atoms or electrons with three spin components, as always in physics there is much insight to be gained by calculating the properties of simplified models. Furthermore, solid-state chemists have been remarkably adept at devising compounds with localized magnetic moments that are good approximations to the ideal theoretical models.
