| Abstract: | In this work, Er3+-doped Cobalt nanoferrite particles (CoErxFe2−xO4; x = 0.0, 0.01, 0.03, 0.05) were synthesised using an optimised citrate-gel auto-combustion method and analysed for structural, magnetic, and electrical properties. Preliminary X-ray diffraction and Raman spectroscopy studies confirm the formation of a single-phase spinel structure. Average crystallite sizes from the Williamson-Hall method are in the range of 28 to 32 nm, which are in close agreement with TEM data. Temperature dependent magnetization The ZFC-FC curves show blocking temperatures that are higher than room temperature. The hysteresis loop clearly demonstrates an increase in saturation magnetization of cobalt ferrite with Er doping concentration. Electrical resistance measurements in different relative humidity conditions (RH 10–95%) and frequencies were done using a high-frequency LCR meter. When compared to pure Cobalt Ferrite, Er doped Cobalt Ferrite samples have lower electrical resistance and higher sensitivity. The variation of resistance with respect to humidity conditions suggested that Er cobalt ferrite nanoparticles are potentially suitable for resistive humidity sensor applications.
