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