Interfaces and solid state reactions of Zr/Fe multilayers

Ferromagnetic Resonance in Fe/Zr Multilayers

“…Therefore, we may argue that in the region of an abrupt decrease in m(dF e )/m(oo) the Fe/Zr MLs, must be looked on as a multicomponent system consisting of the crystalline Fe and Zr and an amorphous FeZr alloy phase. This conclusion agrees with the CEMS measurements [1][2][3].…”

“…A variety of magnetic constituents related to Fe atoms in different surroundings has been revealed using FMR technique. These results agree with the CEMS investigations which revealed the Moessbauer spectra attributed to the interface region between α-Fe and the amorphous FeZr [1,2] and showed that two different Fe states exist in the amorphous phase due to a Fe concentration gradient across the amorphous phase [3]. From the analysis of both the resonance positions and their intensities, we have shown that the remaining unreacted a-Fe in the Fe/Zr MLs rather consists of small grains than continuous sublayers.…”

“…Formation of amorphous phase at interfaces of Fe/Zr multilayers (Mis) during a deposition process has been clearly demonstrated using the conversion electron Moessbauer spectroscopy (CEMS) [1][2][3] as well as using standard magnetic measurements [4]. It has been shown that Fe/Zr Mls can be produced in either predominantly crystalline or completely amorphous state depending on thickness of each constituent.…”

Structure and Magnetic Propertics of Fe/Zr Multilayers

“…For multilayers with λ < 4 nm no crystalline phases were revealed. This is consistent with the result of conversion electron Mössbauer spectroscopy (GEMS) studies presented in the papers [4,5], where the as-deposited iron was shown to be amorphous in Mls with 10 monolayers thick sublayers of Fe and Zr.…”

Microstructure and magnetic properties of Fe/Ti multilayers

“…Relative fraction of a given phase ( F ) (%) estimate the average thickness of the iron layer converted into the amorphous or interfacial FeTi phases. The mixed-layer thickness is[4,21] …”
