Abstract

Samples of La1-xSrxMnO3 (LSMO) complex solution with 0 ≤ x ≤ 0.25 were prepared using the Pechini method. The LSMO solution was then deposited on a quartz substrate using the spin coating technique and annealed at 750°C for an hour. The X-ray diffraction pattern for films with Sr matches with the R3c rhombohedral structure. The surface morphology of the film shows a different structure for a different x with more surface crack formation with Sr increment. The magnetic properties at room temperature showed hysteresis curves for all samples. La1-xSr xMnO3 thin film samples with x = 0.00, 0.05 and 0.10 showed weak ferromagnetic properties while films with x = 0.15, 0.20 and 0.25 are paramagnetic. The sample with x = 0.10 has the highest magnetization value at 12 kOe, which is 0.48 emu/g.
