✦ Synopsis

We solve the Boltzmann's transport equations for conduction electrons in a ferromagnet considering electron-magnon scattering. Such scattering gives rise to a spin dependent Seebeck coefficient, which in turn implies that the spin current can be generated by applying a temperature gradient. We estimate the temperature gradient required for switching a nano-magnet by using spin-transfer torque.
