通过结合X射线共振磁反射率和磁圆二色性测量，获得了铁磁[Gd（50 A）Fe（15，35 A）]（15）溅射多层膜中掩埋Gd /Fe界面处反铁磁（AFM）交换耦合的空间范围zeta（AFM）和强度J（AFM）。zeta（AFM）为4.1（7）A或体Gd和Fe中约1-2个原子间距离; J（AFM）为1050（90）K，与体Fe中的铁磁交换相当。
The spatial extent zeta(AFM) and strength J(AFM) of the antiferromagnetic (AFM) exchange coupling at buried Gd /Fe interfaces in ferrimagnetic [Gd(50 A)Fe(15,35 A)](15) sputtered multilayers is obtained from combined x-ray resonance magnetic reflectivity and magnetic circular dichroism measurements. zeta(AFM) is 4.1(7) A or approximately 1-2 interatomic distances in bulk Gd and Fe; J(AFM) is 1050(90) K, comparable to the ferromagnetic exchange in bulk Fe.
