Comparison of theory and experiment for the magneto-compositional correlation in a ferromagnetic Fe–V crystal

Abstract Polarised diffuse neutron scattering results are presented for the magneto-compositional response function of ferromagnetic Fe 0.865 V 0.135 . The experimental result agrees well with a calculated result obtained from a first-principles ab initio theory that uses modern spin polarised density functional theory adapted to the KKR-CPA method. Importantly, the experimental results extrapolated to zero scattering vector are found to be close to the expected value determined from both the theoretical calculation and bulk magnetisation measurements.
