A well nanocrystalline structured tin substituted nickel ferrite thin film was prepared by chemical co-precipitation method. XRD analysis reveals the average crystallite size as 51 nm and most preferential peak (311) affirms the formation of tin substituted nickel ferrite. The SEM morphology shows the large number of active sites. FT-IR analysis reveals the general nature of ferrite materials. TEM analysis shows the inhomogeneous distribution of particles. Also, the SAED pattern exhibits the polycrystalline nature. From UV analysis, it was observed that material has absorption in visible region at similar to 201 nm. Humidity sensing analysis reveals that material has average sensitivity is 2.08 M Omega/%RH and excellent reproducibility with response and recovery times of 44 and 180 s respectively.
