| Abstract(in English) | We Studied the degradation mechanism of magnetic properties of obliquely evaporeted Co-O film caused by residual gas. It was found that the coercivity(Hc) and squareness ratio(Mr/Ms) decreased with increasing water vapor in residual gas. Higher the water vapor pressure, the more increased easy axis angle from the film plane, and decreased anisotropy field. This suggests the Co vapor scattering by water molecule. In addition, the higher water vapor pressure leads to less oxidation of evaporated Co-O film due to oxygen gas. It is suggested that the strong sticking probability of water molecule to deposition film surface prevents Co film from oxidation. |
