• Measurements of X-ray diffraction, magnetic susceptibility and electric resistivity have been carried out for the Pr_<1.6-x>Y_xSr_<0.4>CuO_y system. The T^* phase is obtained in the composition range 0&≤x&≤0.6. T^* phases are also obtained in Nd_<1.6-x>Ln_xSr_<0.4>CuO_y systems (Ln; Y, Ho, Er, Tm, Yb and Lu), but in a narrow x range such as that of other known T^*-phase compounds. The electric resistivity of the Pr system shows systematic rises accompanied by an increase in Pr concentration. This behavior is similar to that of (Pr-Ln)Ba_2Cu_3O_7 in a higher Pr concentration region. Both the wide composition range and the rise of resistivity may be due to the same factor.
