The magnetic interlayer ordering in Fe(3)/V(14)H x (001) superlattices exhibits dramatic changes on changing the hydrogen concentration. From initial antiferromagnetic (AF) coupling with T N = 370(7) K, the introduction of H (H/V atomic ratio of 0.06) gives rise to ferromagnetic (FM) alignment at room temperature. When cooled, the magnetic ordering exhibits a transition from FM to a canted state below 200 K. Further increase of the hydrogen content (H/V ≈ 1) gives rise to FM-ordering at temperatures between 3…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
