在磁性多层膜中,层间耦合现象具有重要的理论意义,人们做了大量的研究。1986年,在Fe/Cr/Fe(001)3层结构中首次观察到Fe层之间的反铁磁耦合。与此同时,在Gd/Y超晶格中,发现了Gd层之间的铁磁耦合和反铁磁耦合振荡现象。现在证明,层间耦合振荡在磁性多层膜中是一种较普遍的现象。在以Fe,Co,Ni及其合金作为铁磁层,Cu,Ag和Au以及很多3d,4d和5d金属作间隔层的多层膜体系中,都观察到了这种现象。有关Fe-N磁性多层膜的报道很少,本文首次报道以TiN作间隔层的Fe-N/TiN多层膜中,随TiN层厚度变化Fe-N层之间出现的铁磁、反铁磁耦合振荡现象。
In magnetic multilayers, the phenomenon of interlayer coupling has important theoretical significance, and a great deal of research has been done. In 1986, the antiferromagnetic coupling between Fe layers was first observed in the Fe / Cr / Fe (001) 3 layer structure. In the meantime, in the Gd / Y superlattices, the phenomena of ferromagnetic coupling and antiferromagnetic coupling oscillation between the Gd layers were found. It has now been demonstrated that interlaminar coupling oscillation is a more common phenomenon in magnetic multilayer films. This phenomenon has been observed in multi-layer film systems with Fe, Co, Ni and their alloys as the ferromagnetic layer, Cu, Ag and Au, and many 3d, 4d and 5d metals as the spacer. Fe-N magnetic multi-layer film is rarely reported, the first time reported in the Fe-N / TiN multilayer TiN interlayer film, with the TiN layer thickness change Fe-N layer between the emergence of ferromagnetic, anti-iron Magnetic Coupling Oscillation phenomenon.
