Ti子层倾向于使c轴垂直于膜平面对齐，并促进蒸发CoCr膜中柱状晶粒的生长。Ti子层对c轴取向的影响可以类似于外延生长的影响。Ti亚层的存在改善了CoCr薄膜的磁性能：饱和磁化强度Ms、垂直磁各向异性常数、垂直磁滞回线的矫顽力和矩形比均有所增加。Ti子层还用于限制Ms随温度升高的减少。随着温度的升高，Ms的减少较小，并且归因于Ti子层的Ms的增加意味着Ti子层倾向于增加Cr偏析的量。
A Ti sublayer tends to align the c-axes normal to the film plane and to promote the growth of columnar grains in evaporated CoCr film. The effect of a Ti sublayer on the c-axis orientation may be similar to the effect of epitaxial-growth. The Ti sublayer improves the magnetic properties of CoCr film: the saturation magnetization Ms, the perpendicular magnetic anisotropy constant, the coercivity and the squareness ratio in the perpendicular hysteresis loop increase. The Ti sublayer also serves to limit the reduction in Ms with an increase in temperature. The smaller reduction in Ms with increasing temperature and the increase in Ms which are attributable to the Ti sublayer imply that the Ti sublayer tends to increase the amount of Cr segregation.
