Abstract
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 M s, 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 M s with an increase in temperature. The smaller reduction in M s with increasing temperature and the increase in M s which are attributable to the Ti sublayer imply that the Ti sublayer tends to increase the amount of Cr segregation.Keywords
