The experimental conditions play an important role in particle size and in their properties in multifunctional magnetic nanoparticle synthesis. In the present study, magnetite nanoparticles of various sizes were synthesized by microwave irradiation method. The synthesized powder samples were characterized using XRD and SEM which substantiated the formation of magnetic nanoparticle in cubic phase. The particle sizes obtained were 40 nm, 31 nm and 27 nm from TEM micrographs. The FTIR studies confirmed the characteristic band of Fe-O within the range of 574 580 cm-1. The magnetic properties of the samples were measured by vibration sample magnetometer that confirmed ferrimagnetic behavior of magnetite nanoparticles at room temperature. From the present study, it is observed that the microwave irradiation method is a convenient method to produce a wide range of magnetite nanoparticles of desired size for a variety of novel biomedical applications.
