Characterisations of La-Sr-Mn-O (LSMO) Thin Film Fabricated by RF Sputtering

A revisited study of perovskite-based manganite La0.67Sr0.33MnO3 (LSMO) deposited onto corning-glass (CG) substrates is reported here. The LSMO films were fabricated with RF sputtering different deposition times, varying from 60 to 180 min, resulting in thicknesses 35.0–109.7 nm. Rietveld refinements the XRD spectrum showed that samples exhibited hexagonal structures a space group R-3c (167) and remained unmodified structures. Clusters monolayer growth observed morphologies films. Interestingly, average particle size obtained an AFM perceived insignificant variation 31.7–35.6 nm despite film thickness increment. Optical, electrical magnetic properties studied, as particle-size usually has notable contribution changes these properties. It was found optical band gap (Eg) direct time due enhanced surface roughness. temperature dependence resistivity graph fitted percolation model obtain further enlightenment on transport Low-field magnetoresistance (LFMR) for all samples.
