DESCRIPTION:I will start by discussing results on magnetically-doped topol
 ogical insulators (thick films/bulk) of materials such as Cr-Bi2Se3\, whic
 h ideally should exhibit an insulating bulk and an electrically conductive
  surface. We will see how these magnetic and electrical properties could b
 e used technologically. Then\, I am going to show thin film magnetism phen
 omena at surfaces and interfaces such as at EuO/LaAlO3(001) or Graphene/Co
  (Ni). I will then extend these insights to magnetic nanoparticles and see
  that their surfaces can exhibit other long range ordering than their core
 s as present in NiO nanoparticles. Finally if time permits\, I will focus 
 on magnetic surfaces and present recent results from spin-polarised low en
 ergy electron loss spectroscopy on Fe(001)/Ag(001) heterostructures.
