Enhancement of ferromagnetism for VI3 monolayer

Valley splitting and magnetic anisotropy in two-dimensional VI3/MSe2 (M = W, Mo) heterostructures

“…There is still some controversy regarding the MAE of VI 3 . 17,19,20,37,[40][41][42][43][44] By fitting the spin wave gap in the Raman spectrum, the MAE can be estimated as 2.32 meV per cell. 41 However, some MAE values with a large difference, such as 0.29 meV per cell and 31.8 meV per cell, have also been reported.…”

“…16 Although there have been many research reports on the VI 3 monolayer, few studies on the specific application of VI 3 have been reported. [17][18][19][20] Manipulating the valley degrees of freedom for storing information and performing logical operations is an exciting field of both basic and applied research. 21 2D materials such as graphene and transition metal dichalcogenides (TMDs) possess valleys at the inequivalent K 0 and K points in the Brillouin zone, where inversion symmetry breaking together with strong SOC lead to coupling of the spin and valley degrees of freedom.…”

Strain‐Induced Magnetism in MSi2N4 (M = V, Cr): A First‐Principles Study

“…However, FM interaction takes place via the near 90 0 M−N−M bonds arising from the stronger hybridization via the orthogonal p x /p y orbitals, but another path through hybridization via the same p x orbital is prohibited by Hund's rule for the titled compounds. [ 17,21 ] In the equilibrium lattice, the AFM and FM interaction is compensated, resulting in NM. When strain is taken into account, the variation of bond distance makes the splitting of the d sub‐orbitals more obvious.…”

“…[ 12–16 ] Benefiting from the character of small band gap, these 2D FMs are applicable as spin filters or magnetic tunnel junctions. On the other hand, the efficiency of such devices would be greatly improved if FM develops together with half‐metallic (HM) band structure, [ 17 ] whereby electrons in one spin channel display metallic nature, and electrons in the other spin channel demonstrate insulating character.…”

Magnetic interactions and spin excitations in van der Waals ferromagnet VI$_3$

“…For example, large exchange coupling and higher Curie temperature, T C , resulting from a half-metallic ground state, have been reported in Ref. [22]. On the other hand, Yang and coworkers have found a semiconducting ground state and estimated the energy difference between FM and Néel-AFM states, suggesting smaller exchange couplings and T C in monolayer VI 3 [21].…”
