FIRST PhD THESIS WITH RESULTS MEASURED AT BOREAS

Eduardo Solano, from the Universitat Autònoma de Barcelona (UAB) and the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC), obtained his PhD degree last November 2013 with a work about nanocomposite superconducting layers. Some of the measurements were acquired at BOREAS beamline in ALBA Synchrotron.

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 MFe₂O₄ and embedded these nanoparticles inside YBa₂Cu₃O_7-δ superconducting layers.

He used synchrotron radiation techniques, in particular X-Ray Magnetic Circular Dichroism (XMCD) in BOREAS beamline in ALBA to deeply study the structure, composition and behavior of the new nanoparticles nanocomposite.
