Amorphous Co-Ni-P thin film had a lower coercive force and higher squareness ratio. The values of its coercive force and squareness ratio increased when the film was crystallized. Coercive force and squareness ratio of the film which was made up of α-Co and phase of Co2P reached their peak values under the influence of much phosphorous segregating at crystal boundary when heated to 500℃ 1 hour. As temperature was increased successively, the coercive force and squareness ratio of the film decreased because of grain growth and second phase coarsening.

For thinner films, stacking faults are preferred in the scratch process, which increase storage capacity of plastic deformation in the film, and further inhibit the stick slip amplitude in the friction oscillation process. For thicker films, dislocation loops, which glide along slip plane downward to the grain boundary, dominate over the stacking faults, and finally dissipate on the grain boundaries. Since the intergrain stacking faults are inactive in thicker films, the stick slip phenomenon is similar to that in single crystal.

According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall.
