The competition between interlayer and interfacial exchange couplings is found to be temperature dependent in Co(3 nm)/AF/Fe(10 nm) trilayers with AF≡antiferromagnetic NiO, Cr2O3 or Cr. The temperature dependence in trilayers with AF insulating NiO or Cr2O3 spacer layer differs from that with AF metallic Cr. In the insulator case, the enhancement in the interlayer exchange coupling and the reduction in interfacial exchange coupling with increasing temperature results in dominating interlayer exchange coupling at high temperature. In the metallic spacer case, both the couplings decrease with increasing temperature, resulting in decoupling at high temperatures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
