The phase diagram of the Lal.s\_xSmxSro.2CuO 4 system has been investigated by solid state reaction at 1150°C in an oxygen flow. In these conditions, two phases have been found: (i) T-phase which exhibits a homogeneity range for 0~<x~<0.45; (ii) T\*phase which is obtained as single phase only for x
