Single phase Bismuth ferrite (BiFeO3) with high magnetization and polarization was synthesized by
solution evaporation method (SEM) at room temperature. The influence of temperature and size of
nanoparticles on magnetic properties was studied. The prepared Bismuth ferrite (BiFeO3) was characterized
by X-ray diffraction (XRD) to investigate the structure and size of crystal. The average crystallite
size of nanoparticles (NPs) as calculated by X-ray diffraction (XRD) falls in the range of 22–31 nm. The
crystallite size of Bismuth ferrite increased as the temperature varied from 450 °C to 650 °C. Magnetic
properties were studied by using physical properties measurement system (PPMS). It was also observed
that the magnetic properties were directly related to the size and temperature of Bismuth ferrite nanoparticles.
It has been investigated that the magnetization was decreased as the temperature and
crystallite size increased.
