A collection of objects with this property on a la
A collection of objects with this property on a lattice makes up the Ising model, which models ferromagnetism. Applying a correction based on Thomas precession gives the correct gyromagnetic ratio that relates this quantity to the magnetic dipole moment. The operators representing this property are multiples of the Pauli matrices. The coupling of this intrinsic property to another, similar property gives rise to fine structure in atoms. It is conventionally measured in units of h-bar, and in that system, fermions have half-integer values of it. For 10 points, name this intrinsic property of subatomic particles which is distinguished from orbital angular momentum.
