We measured the electron spin relaxation times in GaAs/AlGaAs multiple quantum wells (MQWs) grown on slightly misoriented GaAs(110) substrates. The of the MQW on misoriented GaAs(110) decreased when the misorientation angles were increased. The bulk inversion asymmetry component of the D’yakonov–Perel’ spin relaxation in the misoriented (110) MQWs was calculated to verify the origin of the decrease in the . A comparison between the experimental and calculated results revealed that the decrease in the was attributed to the emergence of in-plane effective magnetic fields in the (110) MQWs due to the misorientation.
