<h2>A. Oxides: bulk, thin films and nanoparticles</h2>
<p>Preparation&nbsp;and study of&nbsp;oxides with interesting magnetic, optical and electronic properties and their correaltion to the structure and the nanosize.</p>
<p>1) structure-properties correlation: the structural repercussion of a high covalency of themetal-oxygen bond; effect of the charge disproportionation;</p>
<p>2) study of the metal-insulator transitions in oxides with strong electronic correlation; 3) comprehension of the magnetic coupling mechanisms and transport in magnetoresistive materials; 5) study of the ordered magnetic structures and charge ordering phenomena in mixed-valence systems; 6) Understanding multiferroism: unveiling the mechanisms of magnetic-electric coupling.</p>
<h2>B. Design, growth and characterisation of perovskite heterosetructures</h2>
<p>as macroscopic objects but also with particular focus on the study of interfaces (Oxidetronics). Optimizing the mechanisms involved in the control of:</p>
<p>1.-Magnetoresitsance/electroresitance from strain fields in piezo/manganite heterosetructures i. e. manipulation of the magnetic and electronic states of the ferromagnetic (manganite)layers byactuation upon the piezoelectric layer;</p>
<p>2.-Magnetoresistance in manganite cuprate heterostructures,determining the relative importance of the mechanism involved ( proximity effects, quasiparticles diffusion, stray fields and electronic reconstruction at the interfaces).</p>
<p>3. The electronic structure at the interface between complex oxides as a new route to doping alternative to the conventional chemical element substitution. This scenario includes the electrostatic doping due to electric field induced depletion and accumulation layers, bandbending at pn junctions or Schottky contacts as well as charge tranfer porcoesses stemming from valence or polarity mismatch.</p>
<h2>C. Nanoparticles</h2>
<p>Preparation of thin films formed by nanometric structures presenting ferromagnetism at room temperature by overcoming the superparamagnetic limit. The nanometric size of the ferromagnetic clusters allows, for instance, the extreme packing needed in high density recording materials or tunneling magnetoresistance needed for spintronic devices.</p>
<h2>D. Transparent films with electronic functionalities</h2>
<p>Design, growth and optimization of new transparent oxide and nitride based thin films and multilayers with tuned electronic and piezoelectric properties.</p>
<h2>E. Hybrid organic-inorganic systems</h2>
<p>Study, design and growth of hybrid devices based in inorganic and organic heterostructures for organic electronics applications as transistors and diodes.</p>
