The external magnetic fields Bext are along [110] direction. a The k-dependent g-factor \({\widetilde{g}}_{k}\) (Eq. (8) and (9)) at k points around the band edges. Each data-point corresponds to a k point. b The global g-factor gΩ = Ω/μBB as a function of nc, where Ω is Larmor precession frequency extracted from spin dynamics at Bext ≠ 0. \({g}^{{{\Omega }}}=\pm \left|{g}^{{{\Omega }}}\right|\) if the excess/excited spin \(\delta {{{{{{{{\bf{S}}}}}}}}}^{{{{{{{{\rm{tot}}}}}}}}}\left(t\right)\) precesses along ± \(\delta {{{{{{{{\bf{S}}}}}}}}}^{{{{{{{{\rm{tot}}}}}}}}}\left(t\right)\times {{{{{{{{\bf{B}}}}}}}}}^{{{{{{{{\rm{ext}}}}}}}}}\). gΩ is close to the averaged g-factor \(\overline{\widetilde{g}}\) defined in Eq. (10). c The effective amplitude of the fluctuation of g factors - \({{\Delta }}\widetilde{g}\) defined in Eq. (11) as a function of carrier density at 10 K.
