dc.description.abstractPolarised neutron scattering is a powerful technique to study magnetism and to enhance the signal-to-noise in the studies of hydrogen-rich materials in biology and organic chemistry. Polarisation analysis unambiguously identifies the scattering pattern of the magnetic structure and excitation and determines the direction of magnetic moment and excitation. Using polarisation analysis in neutron scattering to measure hydrogen-rich materials, we can separately measure the structural signal and the amount of hydrogen in the material, which has long been a challenge in studying organic materials. At ANSTO, polarisation analysis has previously been available on the reflectometer PLATYPUS for thin film and multilayer studies. The operation of a 3He Polarising Station has now provide this capability to the WOMBAT diffractometer for determining magnetic structure down to the atomic level and to the TAIPAN triple-axis spectrometer for studying magnetic excitation and structure. During commissioning tests, we have discovered new details of magnetic structure in multiferroic samples on both instruments. This new development will soon be followed by polarised SANS capability on QUOKKA for magnetic nano-particle and hydrogen-rich material research. Off-specular magnetic scattering on reflectometer PLATYPUS and polarised inelastic scattering on spectrometers PELICAN and SIKA will be made available in the coming months.en_AU
