Anomalous magnetoconductivity in three demensions as a precursor effect of theAnderson localization is discussed for metallic samples of semimagnetic semi-conductors such as Cd.-,Mn.Se. Due to the large effective y-factor (of theorder of 10") arising from rather strong exchange interaction between electronsand magnetic ions (Mn ions), the spin flipping contribution to the quantumcorrection of the condtuctivity saturates at weak magnetic fields (Nl kG). Param-eters appropriate for Cd....Mn....Se gives a relative quantum correction of theconductivity of the order of 10-".
