With respect to the interlayer coupling strength between the free and fixed ferromagnetic layers, the samples have been divided in those with a weak coupling (for tCu &amp;gt; 16\u2009\u00c5) and a strong coupling regimes (for tCu \u2264 16\u2009\u00c5). The FMR behavior in these two regimes is quite different. For the weakly coupled series, there are two well-defined FMR peaks stemming from the free and fixed layers. Their in-plane angular dependences exhibit 180\u00b0 and 360\u00b0 symmetries, respectively. For the strongly coupled SVs, the resonance modes are hybridized and possess features of both layers simultaneously. The main coupling mechanism between the two layers, as concluded from the FMR and MR measurements, is the N\u00e9el \u201corange-peel\u201d magnetostatic interaction, accompanied by a direct exchange due to pinholes in the Cu spacer for tCu &amp;lt; 17\u2009\u00c5.<\/jats:p>","DOI":"10.1063\/1.4798615","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T05:28:08Z","timestamp":1365053288000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["NiFe\/CoFe\/Cu\/CoFe\/MnIr spin valves studied by ferromagnetic resonance"],"prefix":"10.1063","volume":"113","author":[{"given":"A.
