Abstract
In this research project we propose the preparation and structural and electrical (transport and magneto-transport) characterization of magnetic nanostructured oxides films deposited specifically from arrays of ZnO and TiO2 doped with transition metals (Co and Fe). These potentially systems, both theoretically and experimentally, present Curie temperatures above room temperature, enabling their applications on spintronic devices. The project will involve the study of systems in two different scales: thin films and nanostructured powders. Our goal is to study the correlation between the structural characteristics, the dynamics of carriers and their magnetic properties, determining the necessary synthesis conditions to achieve truly ferromagnetic materials. In the following we will present with further details the current stage of knowledge about diluted magnetic semiconductors. In the following sections we have specified the overall objective of the research project and we detail the materials and methods to be employed. Finally we present our considerations regarding the relevance of this proposal and the schedule of activities. (AU)
