An extraordinary form of this behavior exists in systems for which the double exchange mechanism is energetically favorable, as exemplified by Heusler cells. Two important tools for studying systems with this property are a chart that has the as its x- and y-intercepts the coercivity and remanence, respectively, and a lattice model with Hamiltonian given by the sum over cells of the product of two numbers from U one, one number for the cell and one for each of its neighbors. Materials displaying this property exhibit near- constant H-fields on structures separated by Néel or Bloch walls and known as Weiss domains, which break down at the Curie temperature. For ten points, identify this form of magnetism studied with the aforementioned hysteresis loops and Ising model and materials displaying which retain a permanent magnetization when placed in an external field.
