Abstract: 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…
