C. Javier CURIALE

Researcher CONICET

Expertise: Magnetism and spintronics in bulk and nanostructured materials, mainly metals, semiconductors, magnetoresistive materials (natural or artificial) and complex oxides in general. Last years I was focused on the study of the magnetic domain wall (DW) dynamics in thin magnetic films. I was also involved in the implementation of experimental techniques for the characterization of magnetic materials. Also I used different sample fabrication techniques as sol-gel, electrodeposition, sputtering methods and optical lithography as well as micro and nano electric-contacts fabrication by electron lithography.
In my career, some of the most used experimental techniques for sample characterization are: Optical microscopy, scanning and transmission electron microscopy (SEM and TEM), atomic and magnetic force microscopy (AFM and MFM), X-Ray diffraction (XRD), DC magnetization, magnetic resonance (EPR and FMR), Kerr microscopy, thermal expansion and electric transport (DC and AC below 100MHz). I also have general knowledge in vacuum and cryogenic/high temperature (in the 4-1000 K range) techniques.

Background

Permanent position at CONICET (Argentinean Scientific and Technologic Research Council) since 01/04/2009. Actual category: Investigador Independiente (Independent researcher, third tier of a total of five). My working place is the Nanoscience and Nanotechnology Institute (CONICET-CNEA) in Magnetic Resonance Laboratory at the Bariloche Atomic Center of the Argentinean Commission of Atomic Energy. Between 2009 and 2011 I was postdoc at Laboratoire de Photonique et de Nanostructures (LPN-CNRS) and Laboratoire de Physique des Solides (LPS-CNRS) both close to Paris in France. I received my Ph.D. in Physics in 2008 from Instituto Balseiro/Cuyo’s National University working on “Synthesis, structural, magnetic and electric properties of manganite nanotubes” at the Magnetic Resonance Laboratory under supervision of R. D. Sánchez. I received my degree in Physical Sciences from the School of Exact and Natural Sciences of the University of Buenos Aires in Argentina.
