摘要：

The perpendicular magnetic anisotropy constant in giant magnetoresistive granular Co22Ag78 thin films is found to increase and then decrease with annealing temperature, the maximum being about 5x10(5) ergs/cc at an annealing temperature of about 600 K. The observation of domain patterns by magnetic force microscopy is consistent with this result. The origin of the perpendicular magnetic anisotropy is not clear, but suggested to be in an anisotropic Co-Co particle distribution and also due to a surface anisotropy of Co particles.
