The objective of his PhD study was to generate new nanocomposite superconducting layers with magnetic ferrite nanoparticles embedded within the structure. To do so, he developed a new synthetic methodology to produce MnFe2O4 nanoparticles and embedded these nanostructures inside YBa2Cu3O7-δ superconducting layers.
He used synchrotron radiation techniques, in particular X-Ray Magnetic Circular Dichroism (XMCD) at BOREAS beamline in ALBA to deeply study the structure, composition and behavior of the new nanoparticles in the nanocomposite.
