Abstract
Bulk samples of Co1−xNixFe2O4 (x = 0.0, 0.2, 0.4, 0.6, 0.8 1.0) were shaped by a spark plasma sintering (SPS) process. The initial ferrite nano-powders which were prepared using a co-precipitation method were characterized by high-resolution transmission electron microscopy (HRTEM) and Mössbauer spectroscopy. The HRTEM showed nanoparticles with almost 5–35 nm average size. Mössbauer spectrometer is employed to study the magnetic properties of ferrite nano-powders at room temperature. X-ray diffractometer (XRD), field emission scanning electron microscopy (FESEM) coupled with EDS detector for the chemical composition analysis and vibration sample magnetometer (VSM) equipped with FORC software were used to characterize the bulk samples. Without any structural changes to powder samples, a single-phase spinel structure was obtained. In the FE-SEM micrograph, the porosity …
