Unraveling the short-range magnetism in intermetallic core-shell nanoparticles by a new technique, mPDF

Abstract: Magnetic nanoparticles (NPs) are nowadays investigated comprehensively. Our TbCu2 NPs show a core-shell structure in which the core orders antiferromagnetically and the shell is constituted by disordered spins which are the origin of a spin glass behavior at low temperatures. By total magnetic scattering we would obtain not only the local structure of our NPs but also the local magnetic structure and thus, understand the full map of short range magnetic correlations. In fact, for certain applications, in particular biomedicine, it is very important to control these interactions in order to tune the NPs agglomeration. In a previous experiment (ref.1620209) we measured the neutron total scattering of nano-TbCu2 alloys (diffrent particle sizes) but we consider essential to complete the study and measure also the bulk alloy to compare our results.
