Investigations of Crystal Structure and Magnetic Properties of Mn_0.3Fe_2.7O₄/PEO/PMMA/AC Nanocomposites

Abstract

The Mn0.3Fe2.7O4/PEO/PMMA/AC nanocomposites were synthesized using co-precipitation and solid-state reaction methods. The Mn0.3Fe2.7O4/PEO/PMMA/AC nanocomposites were success formed. This was confirmed by characterization using FTIR instrument. The Fe-O, C-O, and C-H2 functional groups were the representation of Mn0.3Fe2.7O4, PEO/PMMA, and AC respectively. Investigation of crystal structure was characterized using XRD instrument. According to X-Ray Diffraction analysis, the crystal size was 10.82 nanometers and the peak of AC was detected on 2θ around 24.85o. In addition, the investigation of magnetic properties was characterized using VSM instrument. This result showed that the Mn0.3Fe2.7O4/PEO/PMMA/AC nanocomposites behave as a superparamagnetic material with a saturation magnetization value was around 12.55 emu/gram.
