Exchange interactions in Fe/Y multilayers

Dipolar interaction, surface anisotropy and alloying effect on magnetic properties of the superlattice Ni1–xFex/Cu

“…Figure 1 shows that the spectrum of each multi-layer contains a number N of distinct modes equal to the total number of monatomic planes making up this multi-layer. This result is in agreement with results of previous works [18,19]. The effect of the intra-layer exchange in J^ produced in the center zone appearance of three distinct groups, each one made up from five close modes.…”
