Abstract
Langmuir-Blodgett (LB) multilayers of ferric arachidate on silicon wafers have been investigated by means of conversion electron Mössbauer spectroscopy (CEMS) and absorption Mössbauer spectroscopy (AMS) at different temperatures between 4.2 K and room temperature. At low temperatures we observe antiferromagnetic ordering in the two-dimensional model substance and determined the magnitude and the orientation of the internal magnetic field. We studied the phase transition and found with increasing temperature a slow decrease of the ordered phase, which has completely vanished at 130 K. In the present state it cannot be decided if we just observe superparamagnetic relaxation or if we observe additional effects arising from the low dimensionality of the system. Comparable measurements on small iron arachidate “LB-particles” have been performed but no significant difference between the films and the small particles can be observed. This has been expected because the two-dimensional structure is mainly preserved in the “LB-particles”.
