Diffuse scattering in NiCoMnTi all-d-Heusler alloys

We aim at measuring the thermal diffuse scattering in single crystals subjected to different heat treatment to analyse the precursor phenomena in the new all-d-Heusler magnetic shape memory alloys. Since the degree of order depends on the heat treatment, this allows to investigate the influence of chemical order on the vibrational properties and phonon softening close to the phase transition.
