Pseudo-single-domain effects and single-domain multidomain transition in natural pyrrhotite deduced from domain structure observations

Main Article Content

H. Soffel


The domain configuration of primary pyrrhotite in a Devonian diabase was studied using the Bitter pattern technique. Due to the uniaxial symmetry the multidomain grains have a rather simple domain structure. The single-domain — multidomain transition occurs at an average particle diameter of 1.6 μm. In the multidomain grains clusters of inclusions seem to produce pseudo-single-domain effects with complicated domain configurations. Such pseudo-single-domain effects are necessary for the interpretation of the magnetically hard component of remanence which cannot be explained by the observed abundance of true single-domain particles alone.
