An application of the Mossbauer effect to the study of some magnetic properties of ilmenite

The investigations described in this thesis clarify and supplement, by means of Mossbauer spectroscopy, the magnetic properties and chemical composition of natural ilmenite and its oxidation products. Natural ilmenite was found by some investigators, using a m.agnetic measurement method, to be weakly ferrimagnetic but was revealed to be in a paramagnetic state by others using Mossbauer spectroscopy. There was an uncertainty about the nature of the magnetic properties of an ilmenite sample which had been partially oxidised by heat treatment. The types of compounds existing in natural ilmenite and its oxidation products were not clearly determined.
