Abstract We have investigated magnetic coupling between semiconductor quantum dots. The antiferromagnetization process based on the interdot exchange interaction has been directly observed using time-resolved spin-dependent photoluminescence measurements. The antiferromagnetic order that proves the interdot exchange interaction energy to be negative is found to exist at temperatures lower than 50–80 K. The spin relaxation time under the antiferromagnetic order is extended to 10–12 ns, an order of magnitude longer than that in isolated quantum dots.
