Bulk layered synthetic Mn-Sb composites, with a gradient structure in morphology and composition towards the surfaces, were fabricated directly in situ under high magnetic field gradient conditions. Both of the primary phases of Mn-Sb binary system, i.e. MnSb and Sb, were found to segregate simultaneously from desired domains with a gradient interface in morphology in those alloys with hypo-eutectic composition. The volume fraction of the segregated phases strongly depended on the product of the magnetic flux density and its gradient.
