  1. Where \({\lambda }_{{{\rm{d}}}}^{{{\rm{Co}}}}\) is diffusion length of orbital current in Co, \({\xi }_{{{\rm{DL}}}0}^{{{\rm{OH}}}}\) is limit of orbital torque at \({t}_{{{\rm{Co}}}}\) = 0, and \({\xi }_{{{\rm{DL}}}}^{{{\rm{SH}}}}\) is total constant spin torque. The uncertainties are standard deviation uncertainties.
