Paper Title:
Analysis of Electron Spin-Spin Interaction in Coupled Quantum Well
  Abstract

Electron spin-spin interaction in asymmetric coupled GaAs/AlGaAs quantum well (QW) is investigated through electron spin precession measurements. In the experiment, the precession (Larmor) frequency of electrons localized in thin and thick QWs are measured by means of polarization- and time-resolved photoluminescence measurements under magnetic field. The Larmor frequency observed in thin well was transformed to that of thick well with increasing excitation power density. This dependence can be reproduced by theoretical calculations, which take into account electron spin-spin interactions in GaAs wells.
