(1-x) La_0.70Sr_0.30MnO₃ (LSMO) – x BaTiO₃ (BTO) (x = 0.10 and 0.20) ceramics were synthesised by chemical route as well as solid-state route for preparation of various compositions in LSMO-BTO (x = 0.10 and 0.20) systems. In this process, LSMO have been prepared by chemical route method and BTO synthesised by solid-state method. The room temperature structure characterisation of all the samples of LSMO-BTO for x = 0.00, 0.10 and 0.20 was carried out. The LSMO have rhombohedral symmetry with space group R-3C; BTO has tetragonal symmetry with space group P4mm. Among all the samples studied, pure and composite samples have shown that the lowest Metal–Insulator (MI) transition temperature occurs for x = 0.20 at 187 K for their temperature-dependent resistivity having the largest value (~ 170 Ω cm). The peak resistivity, ρ_max increases as the MI transition temperature T_MI, goes decreases. Percentage magnetoresistance (MR) variation of LSMO-BTO (x = 0.10 and 0.20) with temperature has also been studied. Analytical analysis shows the % MR data is normally distributed the value of test is greater than 0.05.
