In the present work, we propose a new approach for the ultrafast spin Seebeck effect. Our method exploits Ito - Stratonovich integration scheem. We found that early step spin Seebeck current has nonstationary transversal and longitudinal components; nevertheless, as the magnetization dynamics approaches the steady-state, transversal components decay and remains only longitudinal components
