Study on Magnetic Properties and Gel Formation Process of the Controllable Morphology SrFe12O19 Nano-particles
Using citric acid method synthesizes the controllable morphology SrFe12O19 nano-particles combining the experiment process, the formation sol and gel and the function of citric acid in this process were theories analyzed. The crystal structure, grain size and morphology were tested and studied by means of X-ray diffraction (XRD), Transmission Electron Microscope (TEM) and infrared spectrum (IR). Their magnetic properties were measured by means of vibrating sample magnetometer(VSM),and the relation of morph- ology and magnetic properties were analyzed. Then, the best controllable craft condition of the formation of sol and gel was found.
