Anomalous Particle Size Dependence of Magnetic Relaxation Phenomena in Goethite Nanoparticles
By use of Mössbauer spectroscopy we have studied the magnetic properties of samples of goethite nanoparticles with different particle size. The spectra are influenced by fluctuations of the magnetization directions, but the size dependence is not in accordance with the Néel-Brown expression for supe...
