Biography.João Pedro Esteves de Araújo, 34 yrs old, is Auxiliar Professor at FCUP Physics Departament. He graduated in Physics in 1995 in University of Porto and completed his PhD in 2001 by the same University, in close collaboration with the CERN-ISOLDE laboratory in Geneva. His research is focused in physics of materials, including Nuclear Hyperfine techniques. His actual research interests include the production and study of magnetic nanostructed materials.
Area of scientific activity.I have been actively engaged in research devoted to the preparation and fundamental studies on materials exhibiting strong interplay between electronic, spin, orbital and lattice degree of freedom, in particular the colossal magnetoresistive oxides (manganites) and the high Tc superconducting ceramics, both massive and thin films. Both bulk property measurements (transport and magnetic techniques) and local probe techniques have been used (Perturbed Angular Correlation).More recently I began research on an emerging class of magnetic compounds, where peculiar magneto-structural transitions (martensitic-like) are driven by the electronic fluid. These materials offer, besides fundamental science, tantalizing technological applications, namely for a new generation of magnetic refrigeration and advanced magnetostrictive sensors. I am also working thin film preparation (Ion bem Deposition and Laser Ablation) and physical aspects of nanodevices, in particular spinvalve and Tunnel-Junctions. His actual research interests include the production and study of magnetic nanostructed materials, namelly self organized templates of Nanoporous Alumina obtained by anodic aluminum. |
