在第一性原理（局域自旋密度近似）计算磁晶各向异性能的基础上，我们预测了[111]面心立方Co_1/Ni_2多层膜的磁化强度为垂直取向。然后通过气相沉积生长这种多层膜，发现其具有预测的性质。1 T的饱和磁化强度远大于已知的垂直各向异性磁性多层膜的饱和磁化强度。
On the basis of first-principles (local-spin-density-approximation) calculations of the magnetocrystalline anisotropy energy we have predicted a perpendicular orientation of the magnetization in a [111]fcc Co1/Ni2 multilayer. This multilayer was then grown by vapor deposition and found to have the predicted properties. The saturation magnetization of 1 T is much larger than that of known magnetic multilayers with perpendicular anisotropy.
