Bio
My research career has been focused on the study of magnetic and transport properties of functional complex oxides. The main objective has been to understand the interrelationship between microstructural features and the observed functional properties.
I got my PhD degree at the University of Santiago de Compostela in 1990 with a work about the thermodynamic fluctuations in high temperature copper oxide superconductors which leaded to the preparation, for the first time in a Spanish lab, of high-quality single crystals of YBaCuO. In 1996 I have joined the Laboratoire de Physique des Solides at University of Orsay-France to study the influence of columnar defects created by heavy-ion irradiation in the vortex pinning of superconducting thin films. Vortex matter has relevant interest from a fundamental point of view as a model system with competing interactions but also from an applied point of view to increase the current carrying capabilities of superconductors. In 2002 I have joined the ICMAB-CSIC to study the growth of superconducting wires from chemical methods. I have dedicated an intense effort to thin film preparation and to study the influence of growth kinetics into physical properties. My work has allowed to demonstrate the capabilities of chemical methods to prepare low cost epitaxial thin films with improved properties. We have study the mechanism controlling nucleation and growth of thin films and we have developed novel approaches to improve their vortex pinning properties which resulted in thin films with world record pinning forces.
Later, I got interest in extend this approach to other complex oxides, looking for new routes to prepare nanostructures in oxide thin films. In particular, I have deeply studied the role of epitaxial strain relaxation mechanisms in the formation of long-range ordered nanostructures improving the magnetotransport properties of manganite thin films. This has been the main idea of EU Project DAFNEOX that I have coordinated. As the main results of this project, we have demonstrated the possibility of using nanostructured thin films for guiding self-assembly of nanoparticles, allowing the measurement of transport characteristics of individual particles.
In the last years, I have focused on the study of new oxides with potential application in spintronics. In particular, we have investigated the growth of strontium iridate thin films exhibiting an important spin-orbit effect. This research leaded to the discovery of a tunable resistive switching effect in iridates that has been identified by EU as a new material for ReRAM in the “Excellent Science Innovation” radar (https://www.innoradar.eu/innovation/36215).
Lately, I have been responsible for the set-up of a new ferromagnetic resonance spectrometer that allowed us to measure dynamic spin properties in magnetic films and to perform spin pumping experiments. We have been able to demonstrate Inverse Spin Hall Effect in all-oxide magnetic heteroestructures and opened a new way to get insights into charge-spin interconversion in our lab.
