The substitution of Mn with a low concentration of In (x ≤ 0.20) in the magnetoresistance compound La2/3Sr1/3Mn1-xInxO3 has been investigated. Magnetic properties were analyzed using AC magnetic susceptibility and DC electrical resistance measurements. The metal-to-insulator transition temperature (Tp)decreased from 365 K to 245K as the level of In doping increased, indicating a loss of ferromagnetic order. Similarly, the Curie temperature (Tc) of each sample shifted to lower values with higher In content. X-ray diffraction (XRD) analysis revealed a single-phase perovskite rhombohedral structure. Surface morphology and microstructural analysis using scanning electron microscopy (SEM) indicated that withan increase in Indium concentration up to x= 0.20, grain size diminished significantly, reducing from 15 µm to 2 µm, along with noticeable grain agglomeration.
