The basic parameters of supersymmetric theories can be determined at future e+e- linear colliders with high precision. We investigate in this report how polarisation measurements in and or decays to leptons and t quarks plus neutralinos or charginos can be used to measure (in particular for large values) and to determine the trilinear couplings , At and Ab in sfermion pair production.
