Abstract
Dislocations in the spinel lattice may dissociate into four partials separated by three stacking faults. This dissociation differs slightly from that in corundum. The central stacking fault has a lower energy than the other two and will therefore be much wider. Recently, very thin platelets of BaFe12O19 were obtained and examined with the electron microscope. The lattice of this compound is very similar to that of spinel. Evidence was obtained of dislocations consisting of two partials. Their separation was only about 200 Å so that the other stacking faults, if present, would probably be too narrow to be visible.
