Applying spin-resolved Boltzmann collision integrals, we find that ultrafast demagnetization dynamics is driven by both the equilibration of separated temperatures and chemical potentials of spin-up and spin-down electrons. We set up a system of equation as a simplified phenomenological model to describe the demagnetization dynamics governed by these equilibration processes.
