Abstract Small-angle polarized neutron scattering experiments on ordered invar Fe75Pt25 alloy were performed using a special “inclined” magnetic field geometry. Two contributions to the critical magnetic scattering were studied in the temperature range around TC ≈ 400 K. One of them comes from the pair-spin correlation function. Another contribution is made by the three-spin chiral fluctuations. It is separated from other contributions as the asymmetric part of the polarization-dependent scattering.
