In this paper, the authors report the fabrication of Zn0.2Fe2.8O4 particles from Indonesian sand in the forms of nanopowder and magnetic fluid. The fabrication was conducted by employing a combined coprecipitation-sonochemical method. The analysis of the XRD data presented that the Zn0.2Fe2.8O4 was crystallized in a spinel structure with a lattice parameter of about 8.378 Å. The data analysis of the TEM image showed the Zn0.2Fe2.8O4 particles distributed in nanometric size with a spherical shape. The magnetic investigation showed that the magnetic nanopowder and fluid both had superparamagnetic character. Moreover, the band gap of the Zn0.2Fe2.8O4 particles was about 2.28 eV. These characters open a significant opportunity for the prepared samples to be applied for sensory and antibacterial applications.
