Abstract: In this paper, we review some results obtained in our group in the framework of research projects concerning magnetoelectronic and biomedical applications with advanced magnetic materials. First, we focus on the type of materials used, and then we describe specific magnetoelectronic devices based on spin-dependent tunnelling and magnetic nanoparticles for biomedical applications. Special attention is drawn to the phenomena occurring at the nanometric scale, which in most cases completely determine the observed macroscopic properties.

Keywords: magnetoelectronic applications; biomedical applications; half-metals; magnetic tunnel junctions; inter-grain tunnel magnetoresistance; encapsulated nanoparticles; Spain; advanced magnetic materials; magnetic nanoparticles; nanotechnology; nanoscale.
