Abstract
Magnetic Nanoparticles are so important, on description of their various and charming uses in extensive technical and systematic grounds. Due to their rare optical, microelectronic and magnetic uses metal oxide nanoparticles are the subject to much attention and frequently differ from other nanoparticles. Dextrin coated MnFe2O4 is a renowned soft magnetic material with large value of coercivity and reasonable value of magnetization. The main purpose of this study was to synthesize the dextrin coated manganese ferrite (MnFe2O4) nanoparticles and discuss the magnetic and structural properties of these nanoparticles. Co-precipitation method was used for the preparation of dextrin coated manganese ferrite (MnFe2O4) nanoparticles. Dextrin and metallic chlorides of manganese and iron were used for the synthesis of dextrin-coated MnFe2O4 nanoparticles. Sodium hydroxide (NaOH) was used as a precipitant agent. At 600 degrees C temperature calcination was done for 5 hrs. The X-ray diffractometer (XRD) and Scanning Electron Microscope (SEM) were used to study structural properties of the prepared sample. We confirmed the single-phase dextrin coated manganese ferrite nanoparticles by XRD. Vibrating sample magnetometer at room temperature was used to study the magnetic properties of dextrin coated MnFe2O4 nanoparticles. Fourier Transform Infrared Spectroscopy (FTIR) confirms the attachment of dextrin and other alcohol functional group. In this study, we conclude that by increasing the annealing temperature and growth rate, the size of the nanoparticles may increase. The Sherrer formula was used to calculate the crystallite size, which was 24 nm. At the end, we observed that the large field moment is detected to be insignificant for small particles. The field moment is detected to be significant and touches the bulk value for large particles.
