Effect of high sintering temperature on the cobalt ferrite synthesized via co-precipitation method

Magnetic particle is one of the main elements used in magnetorheological (MR) materials. In this study, the magnetic cobalt ferrite nanoparticles are successfully synthesized via co-precipitation method at different sintering temperatures. The nanoparticles are prepared in neutral condition (pH 7) a...
