Nanophotonic structures with optical surface modes for tunable spin current generation

Abstract

We propose a novel type of photonic-crystal (PC) based nanostructures for efficient and tunable optically-induced spin current generation via the Spin Seebeck and inverse spin Hall effects. It is experimentally...

Enhanced magneto-optical Kerr effect via the synergistic effect of surface plasmon resonance and spin–orbit coupling in Au@Pt nanohybrid layers

“…It is clear that the spin-orbit coupling is proportional to the atomic number Z. In general, heavy 5d transition metals (such as Pt, W, Ta, Hf, etc) exhibit significant spin-orbit coupling effects [34,35]. For example, by contacting with WS 2 , the spin-orbit coupling strength of the graphene is increased by three orders of magnitude [36].…”

Recent advances in 2D TMD circular photo-galvanic effects

“…The manipulation of the valley or the spin degree of freedom may contribute to the fabrication of more energy-efficient information-processing devices than the current charge-based method. [7][8][9][10][11][12] van der Waals (vdW) heterostructures in two dimensions (2D) have become a good choice for fabricating these devices. [13][14][15][16][17][18][19][20][21][22] This is due to the proximity effect used to plan the interaction between the layers and change the properties of different materials.…”

Low power continuous-wave all-optical magnetic switching in ferromagnetic nanoarrays

“…51,52 Additionally, coupling magnetic systems with optical structures can lead to enhanced light absorption. 53,54 The substrates (here Si/SiO 2 or Au/SiO 2 ) on which the nanomagnets are situated have an anti-reflection function, which enhances optical absorption within the nanomagnets up to 65% of the total incident light across a broad frequency range. Sub-diffraction writing and erasing of information is achieved in single nanomagnets.…”
