We have investigated the dependency of the Residual Resistivity Ratio (RRR) on the transport properties of SRO. Although the variation of RRR has a minimal effect on the magnetic properties, its influence is found to be prominent on the transport regime. Films grown under different deposition conditions show a systematic change in RRR, but no such systematic correlation with the MR data, like the reports in the literature. We have observed an unusually high positive MR and a consistent Hall transport study in the ultra-thin films of (111) oriented SRO, which are promising for future studies on this Weyl semimetal candidate.
