采用分子束外延技术在面心立方Cu（001）衬底上生长了亚稳的面心立方Co（001）结构。利用铁磁共振技术研究了这些结构的磁性。给出了不同厚度下的单轴垂直面内各向异性和四重面内各向异性。这两个各向异性被证明是很好地描述了从恒定体积项和1/d依赖的表面项的贡献的总和。给出了四阶畸变对磁各向异性的影响。讨论了各向异性的温度依赖性
Metastable fcc Co(001) structures were grown on fcc Cu(001) using molecular beam epitaxy. Magnetic properties of these structures were studied using the ferromagnetic resonance technique. The uniaxial perpendicular and fourfold in-plane anisotropies are presented for different thicknesses. Both anisotropies are shown to be well described by a sum of contributions from the constant volume term and the 1/d-dependent surface term. The effect of tetragonal distortion on magnetic anisotropies is presented. The temperature dependence of anisotropies is discussed
