Influence of annealing temperature on morphological and magnetic properties of La0.9Sr0.1MnO3

► Successful synthesis of phase pure nanocrystalline La0.9Sr0.1MnO3. ► Effect of annealing temperature ranging from 600 °C to 1200 °C with annealing time of 5 h on magnetic and morphological properties are studied. ► It is observed that magnetic properties are strongly dependent on annealing parameters. ► The sample annealed at 1200 °C shows maximum saturation magnetization and lower coercivity with 52.5 emu/g and 10.7 Oe respectively.
