In this work, we investigated the well width dependence of dynamic nuclear polarization in n‐GaAs/Al0.3Ga0.7As (110) quantum wells. We prepared a set of samples with different well width and thus different g‐factor, and measured the degree of dynamic nuclear polarization in these samples by time‐resolved Faraday rotation measurements. Our calculation, considering simply the projection of time‐averaged electron spins along the external magnetic field, reproduced overall shapes of the nuclear fields as a function of anisotropy of g‐factor.
