The crystal structure in MnPt antiferromagnetic films used in spin-valve films was investigated. The as-deposited MnPt film has strongly (111)-oriented disordered face center cubic structure; the (111) orientation decreases significantly with MnPt film thickness increase after thermal annealing, resulting in a CuAu-I ordered antiferromagnetic MnPt film. We found, through cross-sectional TEM, that the MnPt film thickness also affects the grain sturcture in the annealed spin-valve films.
