Coupled Quantum Well

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.

Dipole Form

A Cavendish-type torsion pendulum, having test masses with 2.5×1022 polarized electrons and "attracting" masses with 8×1023 polarized electrons, is used to search for an anomalous spin interaction of macroscopic range. Competition from magnetic forces is reduced by using ferrimagnetic Dy-Fe masses which exhibit orbital compensation of the electron spin magnetic moments. Combined with magnetic shielding, the sensitivity is 2×10-4 of the gravitational force. Fluctuations set the overall experimental limit at about 5 times this level. Our results set limits on electron spin interactions and on moments which are not of electromagnetic origin. In terms of a standard dipole-dipole form, the limit is 1.5 ×10-12 of the interaction strength between the magnetic moments of the electrons. Compared to previous results, this is a six-cold improvement.
