    The preferred orientation of hexagonal close packed hep grains in magnetically annealed Co and Co-20%Ni alloy was studied by both Schulz's x-ray transmission and reflection methods to clarify the origin of the magnetic anisotropy induced by the magnetic annealing effect. The preferred orientation was first found at a low polar angle α<50° area for both Co and Co-20%Ni alloy. The mechanism of the magnetic anisotropy induced by the field cooling effect was successfully explained qualitatively and quantitatively by this preferred orientation of the grains. The formation of this preferred orientation was discussed in terms of field-induced martensitic transformation. The uniaxial magnetocrystalline anisotropy energy could be the motive energy of the field-induced martensitic transformation.
