Abstract
The magnetic structure factor of the equiatomic FeCo alloy has been me asured in the disordered phase at 1000K by polarized neutron diffracti on. A comparison with the data collected in the ordered phase at room temperature [E. Di Fabrizio et al., Phys. Rev. B40, 9502 (1989) shows marked variations that can be ascribed to the thermal motion of nuclei . From the complete set of data vs temperature, the experimental ion-e lectron linear response function has been deduced and compared to a th eoretical Random Phase Approximation model.
