Abstract
Using a sol–gel route, nanocrystals of γ-Fe2−xYxO3 were prepared with various mole fractions x = 0.00, 0.02, 0.04, and 0.06 of Y. XPS confirmed the Y-doping of the samples and rolled out the occurrence of any oxidation states other than Y3+ and Fe3+. Cubic nanocrystals with space group P4 332 were observed using XRD and FTIR with monotonically decreasing cell parameters and an average size of about 20 nm. The effect of Y-doping on optical properties was investigated using UV–Vis diffuse scattering, and enhanced nonlinear optical parameters were observed for the Y-doped samples. A mixed ferromagnetic and paramagnetic behavior was observed by VSM measurements along with minor changes in other magnetic properties.
