Influence of a Pb buffer layer on structural and magnetotransport properties of Co/Cu multilayers

Diffusion and segregation of substrate copper in electrodeposited Ni–Fe thin films

“…There are some reports on diffusion, segregation and accumulation of copper for thin films produced by vacuum deposition [12][13][14][15][16][17]. The presence of small amounts of the Cu inside the magnetic layer has a negative effect on magnetic properties [18,19].…”

“…For example, one monolayer of Bi on the Cu layer prevents surface segregation and increases magnetic sensitivity of the Ni-Fe layer [12]. Similarly, Pb controls the Cu segregation by out diffusion and segregation to surface [14,17].…”

Atomic separation in Co/Cu/Co magnetic structures study by hybrid X-ray reflectivity – X-ray standing wave approach

“…Depth, nm close optical constant values is typical for an XRR study of Co/Cu systems [17,18]. Marszalek et al [19] reported that periodic multilayered Co/Cu structures grown by thermal sputtering are characterized by a strong smearing of interfaces at a level of 3 nm, which could additionally intricate studying of barriers in Co/Cu structures. Based on this observation, we can conclude that classic XRR measurements are not appropriate for characterization of Co/Cu separation because of their similar densities.…”

Structural-Phase State, Stability of Interfaces and Electrophysical Properties of Two-Layer Film Systems

“…[39]). Не дивлячись на те, що нами не спостерігалося утворення ґрану-льованого стану атомів Fe в матриці Cr (на цьому акцентують також увагу автори [40]), необхідно зауважити, що при формуванні плів-кових систем чи мультишарів в области евтектичного стану мож-ливе утворення [41] вторинних кристалітів (ґрануль) (залежно від концентрації це можуть бути як ґранулі α-Fe, так і Cr) не тільки на межах, але і в об'ємі кристалітів материнської фази.…”
