Crystallographic and magnetic order analysis of a banded limonite
- 19 Downloads
Mössbauer and XRD studies of the light and dark brown parts of a banded limonite showed the presence of kaolinite in the light brown regions. Relaxation behaviour was very well described by a recently proposed model based on magnetic ordering of clusters. The difference in relaxation behaviour of the samples was attributed to different concentrations of non-magnetic impurities.
