摘要：

We carried out neutron diffuse scattering on single crystals of disordered Ni3V, Ni2V, Ni3Cr and Ni2Cr. Intensity maxima show up at (1 1/2 0). The potentials found using inverse CVM, with interactions including 4th neighbors, are temperature independant. Results are in agreement with electronic structure calculations, except in the Ni-Cr system. The transition temperature calculated from the Ni2Cr is half the experimental value (neglected interactions?).
