2.3. Sample characterization
The synthesized magnetic nanoparticles were characterized by different techniques.
The phase structure of nanoparticles was characterized by XRD at room temperature. XRD patterns were obtained using a X'Pert Philips diffractometer, with Cu Kα radiation (λ¼1.5418 Å) at a scanning rate of 0.021 s1 (2θscale) intothe 20–801 interval.
