Abstract: With age bones lose quality being in some cases necessary their replacement. Research is underway on the development of biomaterials to meet the mechanical and biological requirements. One of the most used alloys is Ti6Al4V. The disadvantage of this biomaterial is the formation of a layer of connective tissue between the implant and the surrounding tissue, which makes it difficult to attach to living bone. Ceramic coatings are made on the surface of these metal biomaterials, which improve the communication between the implant and the living tissue.Ti6Al4V substrates have been coated with a bioactive ceramic with composition 7CaO.P2O5.2SiO2 by Pulsed laser deposition (PLD). Layers have been deposited under different substrate conditions and their microstructure and composition have been characterized by XRD and SEM.

Abstract: In this article, we review our recent research on Fe3O4 epitaxial thin films and Fe3O4/MgO/Fe epitaxial heterostructures. More specifically, we report on the magnetotransport properties of Fe3O4 epitaxial films in a wide range of film thicknesses and temperatures, focusing on the anomalous, planar and ordinary Hall effects. We also summarize our insight on the origin of the enhanced magnetic moment found in ultra-thin magnetite films (thickness t < 5 nm). Finally, our work on the growth, and structural and magnetic characterization of heteroepitaxial Fe3O4/MgO/Fe trilayers is presented.
