通过磁化诱导二次谐波(MSHG)测量研究了CoNi/Pt磁性界面随制备条件的变化。已经开发了一种详细的方法来将总的MSHG响应分解为每个界面的磁性和结晶学贡献。虽然CoNi膜(3 nm厚)的体磁性仅与溅射Ar气压有微妙的关系，但界面似乎受到了显著的影响。结果表明，晶体部分探测到界面粗糙度的增加，而磁性部分清楚地揭示了界面面内磁化强度的最大值。
Magnetic CoNi/Pt interfaces are studied as a function of their preparation conditions by magnetization-induced second-harmonic generation (MSHG) measurements. A detailed method has been developed to decompose the total MSHG response into magnetic and crystallographic contributions for each interface. Although the bulk magnetism of the CoNi film (3 nm thick) shows only a subtle dependence on the sputtering Ar pressure, the interfaces appear to be dramatically affected. It can be shown that the crystallographic part probes the increase in the interface roughness while the magnetic one clearly reveals a maximum in the in-plane magnetization of the interface.
