采用对靶直流溅射法在Si（111）衬底上制备了B2型Fe3SiScinFeSi2超晶格。反铁磁耦合超晶格的双线性和双二次耦合常数J1和J2与使用Fe层的类似超晶格相当，尽管Fe3Si的饱和磁化强度约为Fe的一半。作者认为，这是由于在间隔层中形成了有序的量子阱，这主要是由高度取向的Fe3Si层的规则积累引起的。
Ferromagnetic epitaxial B2-type Fe3Si∕FeSi2 superlattices were prepared on Si(111) at room temperature by facing target direct-current sputtering. The bilinear and biquadratic coupling constants J1 and J2 of the antiferromagnetically coupled superlattice were comparable to those of the similar superlattices using Fe layers although the saturation magnetization of Fe3Si is approximately half as large as that of Fe. The authors believe that this is due to the formation of a well-ordered quantum well in the spacers, which is mainly caused by the regular accumulation of highly oriented Fe3Si layers.
