The Ising model deals with this behavior microscopically by considering electrons interacting only with nearest neighbors in a lattice of spin states.
The Ising model deals with this behavior microscopically by considering electrons interacting only with nearest neighbors in a lattice of spin states. Materials with this property exhibit a lag response with changes in an applied field, a phenomenon called hysteresis. This property is characterized by the presence of magnetic properties even after the removal of an external magnetic field, a behavior which ceases above the Curie temperature. For 10 points name this type of magnetism exhibited by such metals as nickel, cobalt, and its namesake, iron.
