Mn0.25Fe2.75O4 nanoparticles have been successfully synthesized using a coprecipitation method. PEG 6000 polymer was added on the synthesis of Mn0.25Fe2.75O4 which aimed at decreasing and preventing the emergence of aggregation between particles. The characterization of the phase structure, absorption of functional groups, and distribution of Mn0.25Fe2.75O4-PEG 6000 nanoparticles have been successfully performed using the instruments of XRD, FTIR, and Small Angel X-Ray Scatterring (SAXS) respectively. XRD characterization results showed that the phase structure formed was in the form of magnetite and corresponded to the Inorganic Crystal Structure Database (ICSD) number 9013529. The bond of Fe-O and Mn-O consecutively on the wave numbers of 430 and 482 cm-1 which were the representation of Mn0.25Fe2.75O4 material have been successfully confirmed through the characterization using FTIR, meanwhile the stretching vibrating on the wave numbers of 1251, 1352, 1472, and 1629 cm-1 for functional groups C-H is the representation of PEG template which has the chemical structure of -OH[-CH2-CH2-]n OH. SAXS characterization showed that the primary and secondary particle sizes from the Mn0,25Fe2,75O4-PEG 6000 nanoparticle were 3.08 and 11.4 nm respectively. The value is the optimum results of the PEG 6000 template influence on the synthesize of Mn0.25Fe2.75O4-PEG 6000 nanoparticles which are potential to be a raw material of magnetic fluid and gel on hyperthermia therapy. © Published under licence by IOP Publishing Ltd.
