Nanostructured actinide materials

Status

 
Terminated - Planned from March 2007 till September 2008

Goals

Pioneering works on nanostructured actinide-based systems point to a high sensitivity of 5f electronic behaviour to the variable structure obtainable in these systems. The present project aims at studies of the variations of the 5f magnetism. The primary target is electronic structure of Pu-based systems (as Pu-U and Pu-Am alloys) from the point of view of variable 5f localization, as depending on composition and thickness of ultrathin layers, using PES (XPS, UPS) as a main tool. The other target is ferromagnetic U compounds (UH3, UGa2), which may be considered as the 5f component of future magnetic Fe- or Co-based multilayers. Several systems (thin films of variable microstructure) will then be prepared by using the existing sputter deposition.

Expected results

The prepared structures will be studied by photoelectron spectroscopy, various X-ray diffraction techniques including GLAXRD, SQUID magnetometry, electronic transport techniques. To address complex systems, a newgeneration sputter source with 3 independent targets needs to be developed. It will be built and tested at CUNI and fitted to the existing photoelectron spectroscopy facility at ITU to enhance the overall capability of the experimental device.
