Spin-ip rates in GaAs quantum dots can be quite slow, thus opening up the possibilities to manipulate spin states in the dots. We present here estimations of inelastic spin-ip rates mediated by hyperΓΏne interaction with nuclei. Under general assumptions, the nucleus mediated rate is proportional to
