Title: Complex characterization of magnetic fluids by Mossbauer spectroscopy
Published In: Romanian Reports in Physics, Vol. 58, No. 3, pp. 273-280
Description: Samples of ferrofluids, consisting in ferrite-like nanoparticles coated with double layers of surfactants and dispersed in water were studied by X-ray diffraction and temperature dependent Mössbauer spectroscopy. Information about the particle mean size, the size dispersion and the effective anisotropy constant was obtained for each sample. Different magnetic relaxation processes were observed in dependence on the surfactant layers.
