Abstract: (1494 Views)
Magneto-optical Faraday effect is a common method for investigating of the magnetic property of materials. In this study, effects of different concentration of iron oxide ferrofluids were investigated with magneto-optical Faraday method. Nanoparticles were synthesized by co-precipitation method and stabilized by adding citric acid. Faraday measurement demonstrated that by increasing the concentration of the ferrofluid, the Faraday rotation and saturation magnetization increased. In the second study, the ferrofluid Brownian’s relaxation time was also evaluated. Results showed that the relaxation time increased by increasing ferrofluid concentration.
