Investigating the Effect of Ultrasound Intensity on the Magnetic Properties of Magnetite Nanostructures Synthesized by Sonochemical Method

In this article, the synthesis of magnetite nanostructures was successfully carried out by sonochemical process. method, stoichiometric amount iron chlorides (FeCl3.6H2O and FeCl2.4H2O), ammonia (NH3) polyvinylpyrolidone (PVP) were used to synthesize pure Fe3O4 nanoparticles. The effect initial sonication power ultrasonic device on size morphology final products as one effective parameters investigated. For this, sonicator evaluated at 90, 70, 50 30 W 40°C. Characterization nanoparticles done transmission electron microscope (TEM) X-ray powder diffraction (XRD) its magnetic properties investigated vibrating sample magnetometer (VSM). Investigation XRD pattern after annealing showed that phase formed during TEM images determined be 10-50 nm. results increasing system reduced particle improved
