Effect of surface hybridization on RKKY coupling in ferromagnet ...

WebThe RKKY coupling and its voltage dependence is measured as a function of the Ru interlayer thickness, along with the effects of repeated voltage cycling. The Li ions both change the amplitude of the RKKY coupling and its phase, leading to the ability to switch the RKKY coupling between ferromagnetic and antiferromagnetic with applied voltages.

RKKY stands for Ruderman–Kittel–Kasuya–Yosida. It refers to a coupling mechanism of nuclear magnetic moments or localized inner d- or f-shell electron spins in a metal by means of an interaction through the conduction electrons. The RKKY interaction was originally proposed by Malvin Ruderman and Charles Kittel of the University of California, Berkeley, as a means of explaining unusually broad nuclear spin resonan… WebApr 6, 2016 · The RKKY coupling and the Kondo effect have of course the same origin in the screening of the impurity by the conduction electrons. But I find it difficult to answer the main question, because it is obvious that adding another impurity spin will change the correlations compared to the single impurity case. church of saint ann in lawrenceville nj

WebFor this purpose, we exploit the strength of the exchange coupling of the RKKY type between the films which allows tuning the phase of the transmitted spin waves in the wide range of angles [−π/2; π/2]. We combined the phase-shift dependency along the interface with the lens equation to demonstrate numerically the metalens for spin waves.

WebFor this class, the RKKY interaction decays spatially with a fast power law . Away from half filling, we show that the exchange coupling in graphene can be controlled across the quantum critical region by gating.
