Lecture: 'Magnetic Nanoparticles: Versatility of the core/shell morphology to tune different properties'

Magnetic Nanoparticles: Versatility of the core/shell morphology to tune different propertiesNowadays  magnetic  nanoparticles  are  widely  used  in  many  applications  as  high  density  data  storage, high performance magnets, or biomedical application as MRI, magnetic hyperthermia. In  particular,  new  synthesis  and  physical  fabrication  methods  allow  to  combining  in  a  single  nanoparticle two or more components, with controlled size and high quality of interfaces, which open  a  wide  range  of  new  possibilities  to  develop  bifunctional  materials.  The  presence  of  interfaces  in  core/shell  bimagnetic  nanoparticles  also  introduces  additional  interactions  that  could radically modify the static and dynamic magnetic behavior of the systems, and provides supplementary tools to optimize and control their physicochemical properties. In this talk, I will present  the  strategies  followed  to  design  and  fabricate  different  core/shell  nanoparticles  for tuning  its  magnetic  anisotropy,  its  relaxation  mechanism  to  optimize  the  heating  efficiency  in  magnetic hyperthermia experiments or tuning the switching field in tunnel magnetoresistance nanostructures.
