Abstract
Iron microcrystal ranging in size from 70 to 450 Å have been investigated by the Mössbauer effect. There is, compared to the bulk value, a small enhancement of the magnetic field at the site of the nucleus of about 1% which can be interpreted as due to the demagnetisation field of the microcrystals and their geometric arrangement. The observed drastic size and temperature dependent lowering of the Debye Waller factor cannot be explained by a change of the Debye temperature of the microcrystals. Two different models are proposed to explain the effect.
