Spinel cobalt-nickel ferrite nanoparticles, having a particle size of around 40 nm, were produced by undergoing a succession of synthesis routes comprised of chemical co-precipitation, hydrothermal treatment (HT), and etching in hydrochloric acid (ET) of concentration 2.0 mol/L. The room temperature high-field Mössbauer spectra were analyzed in detail and significant spin canting associated with Fe3+ ions at both A- and B-sites were observed for both the HT and ET samples in the presence of external magnetic field of 5 T. The effect of etching on various Mössbauer parameters such as the hyperfine field distribution, isomer shift, quadrupole splitting and the linewidth was noted. The A site and B site canting angles of the HT sample were respectively 17° and 22°, while canting angle of approximately 13° was observed for both A and B sites in the ET sample.
