One is the usual magnetization $\\vec{M}$. The other is the non-equilibrium quantity $\\vec{m}$, called the spin accumulation, by which the non-equilibrium spin current can be transported. $\\vec{M}$ represents a correlated distribution of a very large number of degrees of freedom, as expressed in some equilibrium distribution function for the excitations; we therefore forbid $\\vec{M}$ to diffuse, but we permit $\\vec{M}$ to decay.
