Abstract

Ferrite nanoparticles have become interesting materials originating from their performances in many applications. In this paper, the preparation metal-doped ferrites in the system of Fe_2.9Cr_0.1O₄ nanopowders is reported. The Cr_0.1Fe_2.9O₄ nanopowders were utilized to produce ferrofluids. The Indonesian sand was used as a raw material to prepare the samples using co-precipitation route. The Fe_2.9Cr_0.1O₄ particles structured in cubic spinel with the particle size and lattice parameter of about 9.4 nm and 8.36 Å, respectively. The band gap energy of the Cr_0.1Fe_2.9O₄ nanopowders was 2.26 eV. Furthermore, the saturation magnetization of the powder was higher than that of the fluid as the effect of particle size and aggregation.
