The phenomenal growths of information technology and related fields have warranted the
development of new class of materials. Multifunctional oxides, magnetic-semiconductors, multiferroics
and smart materials are just a few examples of such materials. They are needed for the
development of novel technologies such as spintronics, magneto-electronics, radhard electronics, and
advanced microelectronics. For these technologies, of particular interest are some solid solutions of
ilmenite-hematite (IH) represented by (1-x) FeTiO3.xFe2O3 where x varies from 0 to 1; Mn-doped
ilmenite (Mn+3-FeTiO3) and Mn-doped pseudobrookite, Mn+3-Fe2TiO5
(PsB). These multifunctional oxides are ferromagnetic with the magnetic Curie points well above the
room temperature as well as wide bandgap semiconductors with band gap Eg > 2.5 eV. This paper
outlines: (a) processing of device quality samples for structural, electrical and magnetic
characterization, (b) fabrication and evaluation of an integrated structure for controlled magnetic
switching, and (c) the response of the two terminal non-linear current-voltage (I-V) characteristics
when biased by a dc voltage. Subsequently, we will identify a few microelectronic applications based
on this class of oxides.
