Abstract

With this project we will enhance ongoing research on heterostructures based on coupled magnetic-optical and magnetic-magnetic nanoparticles. The project aims to obtain and control new complex nanoheterostructures composed different types of optical and magnetic nanoparticles, as well as to advance the understanding of phenomena, such as charge or spin transfer, or other structural phenomena. In this same sense, this project also proposes investigate the interface effect between the constituents on the macroscopic observables and how these can be improved and tailored for technological or biomedical applications. Other of the fundamental targets of the project is to understand the origin of new magnetic properties only observed on these types of nanostructures. (AU)
