We report several preliminary studies of the time dependence of B 0 s -B 0 s and B 0 d -B 0 d mixing using a sample of 400,000 hadronic Z decays collected by the SLD experiment at the SLC.The study of B 0 d -B 0 d mixing determines a value of ∆m d = 0.503±0.028(stat)±0.020(sys)ps-1 .In the study of B 0 s -B 0 s mixing, oscillation frequencies up to ∆m s < 11.1ps -1 are excluded at 95% C.L. The combined sensitivity is 13.2 ps -1 .
