Abstract
A series of synthetic acicular and natural goethite samples was examined by Mössbauer spectroscopy in the temperature range 5 to 290 K. From the temperature dependence of magnetic moment fluctuations the anisotropy constant has been estimated and the results have been compared with results of the magnetic measurements.
