In this study, the magnetic properties of Si(100)/X5/(Co0.3/Ni0.5)3/Y5 (X: Pt, Cu and Y: Pt, Cu, all thicknesses are nm) multilayers were investigated using ferromagnetic resonance technique (FMR). In sample sets all layers (buffer, cap, and Co) were grown by magnetron sputtering while Ni sub-layers were grown by molecular beam epitaxy (MBE) at high vacuum. The effective magnetic anisotropy is 300 mT when copper is used as the buffer and cap layer, 290 mT when the buffer layer is copper, and the cap layer is Pt. On the other hand, it is seen that the effective magnetic anisotropy is 350 mT when Pt is used as buffer and cap layer, and 150 mT when Pt buffer and Cu cap layer are used. Furthermore, magnetic easy axis is out of plane when the Pt buffer layer is used, while the magnetic easy axis is parallel to the plane when the Cu buffer layer is used. The results show that the buffer and cap layers of Co/Ni thin films, which are frequently used in the field of spintronics influence the magnetic properties.

Bu çalışmada, Si(100)/X5/(Co0.3/Ni0.5)3/Y5 (X: Pt, Cu ve Y: Pt, Cu, tüm katmanların kalınlığı nanometre) çok tabakalarının manyetik özellikleri ferromanyetik rezonans tekniği kullanılarak incelenmiştir. Numune setlerinde tampon, kapak ve Co katmanları magnetron püskürtme tekniği ile büyütülürken, Ni alt katmanları yüksek vakumda moleküler ışın epitaksisi (MBE) ile büyütüldü. Etkin manyetik anizotropi, tampon ve üst katman olarak bakır kullanıldığında 300 mT, tampon katman bakır ve üst katman Pt olduğunda 290 mT'dir. Öte yandan tampon ve kapak tabakası olarak Pt kullanıldığında etkin manyetik anizotropinin 350 mT, Pt tampon ve Cu üst tabakası kullanıldığında ise 150 mT olduğu görülmektedir. Ayrıca, Pt tampon tabakası kullanıldığında manyetik kolay eksen düzlem dışındayken, Cu tampon tabakası kullanıldığında manyetik kolay eksen düzleme paraleldir. Sonuçlar, spintronik alanında sıklıkla kullanılan Co/Ni ince filmlerde tampon ve kapak katmanların manyetik özellikleri etkilediğini göstermektedir.
