Coexistence of ferromagnetism and spin-orbit coupling by incorporation of platinum in two-dimensional VSe
E. Vélez-Fort, A. Hallal, R. Sant +20
We report on a novel material, namely two-dimensional (2D) VPtSe alloy, exhibiting simultaneously ferromagnetic order and Rashba spin-orbit coupling. While ferromag…
Rashba-type Dzyaloshinskii-Moriya interaction, perpendicular magnetic anisotropy and skyrmion states at 2D materials/Co interfaces
Ali Hallal, Jinghua Liang, Fatima Ibrahim +3
We report a significant Dzyaloshinskii-Moriya interaction (DMI) and perpendicular magnetic anisotropy (PMA) at interfaces comprising hexagonal boron nitride (h-BN) and Co. By compa…
Current-driven domain wall dynamics in ferrimagnetic Ni-doped Mn4N films : very large domain wall velocities and reversal of motion direction across the magnetic compensation point
Sambit Ghosh, Taro Komori, Ali Hallal +11
Spin-transfer torque (STT) and spin-orbit torque (SOT) are spintronic phenomena allowing magnetization manipulation using electrical currents. Beyond their fundamental interest, th…
Giant perpendicular magnetic anisotropy enhancement in MgO-based magnetic tunnel junction by using Co/Fe composite layer
Libor Vojáček, Fatima Ibrahim, Ali Hallal +2
Magnetic tunnel junctions with perpendicular anisotropy form the basis of the spin-transfer torque magnetic random-access memory (STT-MRAM), which is non-volatile, fast, dense, and…
Unveiling multiferroic proximity effect in graphene
Fatima Ibrahim, Ali Hallal, Daniel Solis Lerma +3
We demonstrate that electronic and magnetic properties of graphene can be tuned via proximity of multiferroic substrate. Our first-principles calculations performed both with and w…
Very large Dzyaloshinskii-Moriya interaction in two-dimensional Janus manganese dichalcogenides and its application to realize skyrmion states
Jinghua Liang, Weiwei Wang, Haifeng Du +5
The Dzyaloshinskii-Moriya interaction (DMI), which only exists in noncentrosymmetric systems, is responsible for the formation of exotic chiral magnetic states. The absence of DMI…
