In this study, magnetite (Fe3O4) nanocrystals with a size range of 25 nm were prepared by the facile chemical coprecipitation method by a surfactant-assisted from the solution of FeCl3.6H2O salt-solution. In the process, we used octanoic acid as surfactant. In addition, the magnetic hysteresis measured shows that the rods obtained display ferromagnetic properties at room temperature. The samples were...
Nanocrystalline nickel ferrite (NiFe 2 O 4 ) powder was prepared by a co-precipitation method from Ni and Fe chlorides. The as-prepared samples were characterized by powder X-ray diffractometry (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and vibrating sample magnetometry (VSM). SEM and TEM indicated...
