Eutectic Bi/MnBi magnetic alloy was prepared by directional solidification.When the growth rate,R>2 cm/h,the MnBi fibre spacing,λ,distributed homogeneously in Bi matrix,follows λ~2R=constant.The thermal gradient.G_L,does not influence λ.The magnetic property,B_r of Bi/MnBi alloy decreases with the increase of R and increases with the increase of G_L.
