Tunable magnetocrystalline anisotropy and valley polarization in an intrinsic ferromagnetic Janus 2H -VTeSe monolayer

Tunable polarization properties of charge, spin, and valley in Janus VSiGeZ4 (Z = N, P, As) monolayers

“…Strain engineering has been proposed to be an effective way to modulate the magnetic properties of 2D materials. 68–72 Here, the strain effect on the magnetic properties of VSiGeN 4 and VSiGeP 4 is shown Fig. 5.…”

“…This property has been revealed in other 2D ferrovalley materials. 25,68 When considering SOC, the calculated band gap of VSiGeN 4 is 0.14 and 0.23 eV by using GGA + U and HSE06 methods, respectively. The band structure by using HSE06 with SOC is shown in Fig.…”

Ferrovalley and topological phase transition behavior in monolayer Ru(OH)2

“…42,[44][45][46] T c has been predicted in 2D magnets even with in-plane anisotropy. 42,43,47 So, the evaluation of T c for monolayer Ru(OH) 2 is performed using MC simulations. Meanwhile, according to the Mermin-Wagner theorem, 48 the ferromagnetic order is prohibited in 2D materials with continuous spin symmetries.…”

Optical spectrum of ferrovalley materials: A case study of Janus H-VSSe

“…Recently, more and more ferrovalley materials have been discovered, such as H-VSe 2 , [15,16] H-LaBr 2 , [17] H-GdI 2 , [18] H-FeCl 2 , [19,20] Nb 3 I 8 , [21] MN 2 H 2 [22] and VSi 2 N 4 [23,24] and their Janus structures, [9,[25][26][27][28][29][30][31] in which not only the spatial inversion symmetry but also the time reversal symmetry is broken. Ferrovalley materials are promising materials for spintronic and valleytronic devices, but the optical properties of ferrovalley materials in terms of exciton effects have yet to be studied.…”
