Abstract
A method is developed to analyze the in-plane magnetic anisotropy from surface morphology for amorphous films. The lateral sizes along radial direction (R RD ) and tangent direction (R TD ) of rotational substrate, which are extracted from the surface morphology of Co 66.3 Zr 33.7 amorphous films, are used to calculate stress anisotropy energy E σ . It is found that E σ is consistent with the magnetic anisotropy energy K μ for the samples deposited on Si (1 0 0) substrate and then a relationship K μ ∝ 1/R RD - 1/R TD can be obtained. This method is sensitive to the initial state of substrate so its application range is discussed.
