At low temperature, this quantity equals its value at absolute zero times the expression “1 minus temperature over critical temperature (-5[1])raised to the three-halves power.” Between Bloch domains, this vector rotates continuously about the normal of the Bloch wall plane. The volume bound (-5[1])current density equals (10[1]-5[1])the curl of this quantity. (10[2])This quantity is the order parameter of the Ising model, (10[1])in which it spontaneously (10[2])emerges (-5[1])as temperature is decreased in a phase transition. (-5[1])The H-field (-5[1])equals the B-field (-5[1])divided (10[1])by the permeability of free space minus this quantity. (10[1])When increasing the applied field no longer increases this quantity, a ferromagnet has become saturated. For 10 points, (-5[1])name (-5[1])this vector defined (-5[1])as the magnetic (10[1])dipole moment per unit volume, (10[1]-5[2])the magnetic (-5[1])analog of electric (-5[1])polarization. ■END■ (10[7]0[40])
