Integrated Infrastructure Initiative for Neutron Scattering and Muon Spectroscopy (JRA5: Polarised Neutron Techniques)

01.01.2004 - 31.12.2009
Research funding project
The development of new superconductors, molecular magnets, spin electronic and magnetic nanostructures are at the forefront of condensed matter research. Polarized neutron scattering provides exceptional possibilites for detailed understanding of the mechanisms involved. Measurment of the vector properties of the neutron polarization provides a unique way of recovering the significant directional and phase information lost when only neutron intensities are measured. The changes in the direction of the neutron spin that take place on scattering by a magnetic dipolar field are highly dependent on the relative orientations and can be measured very precisely using neutron polarimeters. On the other hand, the Larmor precession of neutron spin in magnetic field allows attachment of a "Larmor clock" to every neutron. Such a Larmor labelling opens the possibility for the development of "unusual" neutron scattering techniques, where the energy (momentum) resolution does not require the initial and final states to be well selected. This decoupling results in an extremely high energy (momentum) resolution that is not achievable in conventional neutron spectroscopy (diffraction) because of intolerable intensity losses.
