We present a theory of both the itinerant carrier-mediated RKKY interaction and the virtual excitations-mediated Bloembergen-Rowland (BR) interaction between magnetic moments in graphene induced by proximity effect with a ferromagnetic film. We show that the RKKY/BR interaction consists of the Heisenberg, Ising, and Dzyaloshinskii-Moriya (DM) terms. In the case of the nearest distance, we estimate the DM term from the RKKY/BR interaction is about 0.13 meV for the graphene/Co interface, which is…

Significant Dzyaloshinskii–Moriya interaction at graphene–ferromagnet interfaces due to the Rashba effect

It is demonstrated that chiral spin textures are induced at graphene/ferromagnetic metal interfaces, and this work paves a path towards two-dimensional-material-based spin–orbitronics.

Anatomy of Dzyaloshinskii-Moriya Interaction at Co/Pt Interfaces.

The main features and microscopic mechanisms of DMI in Co/Pt bilayers via first principles calculations are unveiled and it is found that the large DMI of the bilayers has a dominant contribution from the spins of the interfacial Co layer.

Thickness dependence of the interfacial Dzyaloshinskii–Moriya interaction in inversion symmetry broken systems

Here it is demonstrated an experimental technique to straightforwardly observe the IDM interaction, namely Brillouin light scattering, and the non-reciprocal spin wave dispersions allow not only the determination of theIDM energy densities beyond the regime of perpendicular magnetization but also the revelation of the inverse proportionality with the thickness of the magnetic layer.

RKKY coupling in graphene

We study the carrier-mediated exchange interaction, the so-called RKKY coupling, between two magnetic moments in graphene using exact diagonalization on the honeycomb lattice. By using the…

Interlayer Dzyaloshinskii-Moriya Interactions.

It is shown by means of atomistic calculations that in heterostructures an interlayer coupling of the Dzyaloshinskii-Moriya type across a spacer can emerge and this interaction yields nontrivial three-dimensional spin textures across the entire trilayer, which evolve within as well as between the planes and, hence, combine intraplane and interplane chiralities.

Direct observation of the Dzyaloshinskii-Moriya interaction in a Pt/Co/Ni film.

Linewidth measurements reveal that the lifetime of the magnons is asymmetric with respect to their counter-propagating directions, and the lifetime asymmetry is dependent on the magnon frequency, being more pronounced, the higher the frequency.

Proximity-induced exchange and spin-orbit effects in graphene on Ni and Co

The induced-proximity effects of nearly commensurate lattice structure of a graphene layer on Ni(111) and Co(0001) substrates in the AC stacking configuration are addressed through an analytical…

We study the exchange interaction $J$ between two magnetic impurities in graphene (the RKKY interaction) by directly computing the lattice Green's function for the tight-binding band structure for…

RKKY interaction and intervalley processes in p-doped transition-metal dichalcogenides

We study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction in p-doped transition metal dichalcogenides such as MoS$_2$ and WS$_2$. We consider magnetic impurities hybridized to the Mo d-orbitals…

Reversible control of Dzyaloshinskii-Moriya interaction at the graphene/Co interface via hydrogen absorption

Using first-principles calculations, we investigate the impact of hydrogenation on the Dzyaloshinskii-Moriya interaction (DMI) at graphene/Co interface. We find that both the magnitude and chirality…
