ELECTRONIC STRUCTURE AND MAGNETISM OF SOME 3d - TRANSITION METAL CHALCOGENIDES

5.1 INTRODUCTION 

This chapter presents the electronic structure and magnetic properties of some of the 3d-transition metal chalcogenides studied within the framework of the one electron band theory. These chalcogenides, like the oxides described in the earlier chapters, exhibit exotic behaviour with respect to their electrical and magnetic properties. The electrical and magnetic properties range from metallic to insulating and Pauli paramagnetism to ferro or antiferromagnetism. Both localised and itinerant electron behaviour are found to exist among these systems and in some systems the transition from localised to collective electron states have been found to occur as a function of temperature, pressure, chemical composition etc. [40,41].
